How Effective Is Birth Control If My Partner Cums Inside Me?

How Effective Is Birth Control If He Cums Inside You?

Birth control is, statistically speaking, 95% effective if he cums inside — as long as the method is applied correctly each and every time you have sex. 

According to the study we referenced above, 61% of women who relied on condoms said they were not used during every instance of intercourse (or one was put over the penis “late” into the activity).

Additionally, 38% of women said they’d missed at least one birth control pill over a three-month period — which can and does affect the method’s efficacy.

As we mentioned earlier, when contraceptives were used correctly, their failure rate is only 5% overall (but varies considerably by method, more below).

Birth control can prevent pregnancy even if your partner cums inside you although the effectiveness ultimately depends on the exact method(s) you’re using and whether it is being used consistently and correctly.

The Pill (Oral Contraceptives)

The combined pill is 99% effective when used perfectly while the progestogen-only pill is more than 99% effective.

But because many women occasionally miss taking their daily pill or take it at a different time during the day at some point, this birth control method is really only about 93% effective.

According to this study, between 3 and 7% of women on the pill become pregnant each year.

Additionally, the pill may also be less effective when taking certain antibiotics or other medications, or if you have vomiting or diarrhea for more than two days.

For these reasons, it can be helpful to use a backup birth control method even if you are on the pill.

But if you’re wondering, “Can he come in me if I’m on the pill?” the answer is generally yes — as long as you take it at the same time, each and every day, without fail.

The Birth Control Shot (Depo-Provera)

The shot is over 99% effective if you get it on time, meaning every three months.

In reality, the shot is about 96% effective because many people do not get their shots on time — about 6 out of every 100 women on Depo-Provera become pregnant each year.

The Birth Control Implant (Nexplanon)

Also known as an etonogestrel subdermal implant, this nifty in-arm device is over 99% effective and one study found it to be 100% effective — in part because there is no room for user error.

Once placed, the implant remains intact, providing continual (and uninterrupted) distribution of hormonal therapy that prevents pregnancy for five years at a time.

The Intrauterine Device (IUD)

IUDs are also over 99% effective, resulting in fewer than 1 pregnancy per 100 women each year.

Like the implant, there is no room for mistakes when it comes to IUDs because they are inserted by a doctor and remain in place for 3 to 12 years, depending on the type.

As soon as you get your IUD removed, it no longer protects you from pregnancy and you can get pregnant right away.

Vaginal Ring

Vaginal Rings (like NuvaRing, EluRyng, and Annovera) are between 91 and 99% effective depending on whether they’re being used correctly.

Inserted manually and worn for three weeks on, and one week off, they deliver hormones for varied lengths.

Both NuvaRing and EluRyng provide hormones for five weeks, while Annovera can deliver hormones for up to one year.

Diaphragm (Cervical Cap)

If a diaphragm is inserted correctly with the use of spermicide, it is between 92 and 96% effective at preventing pregnancy.

This method of birth control should be used before sexual activity, however, it is important to note that if a diaphragm is left in for longer than 3 hours, more spermicide should be applied.

Condoms

Condoms are 98% effective at preventing pregnancy when used perfectly.

Realistically speaking, however, condoms are about 87% effective because they can slide off, break, or be forgotten entirely.

Additionally, 61% of women in one study noted that they either did not use a condom each and every time they had sex, or the condom was applied “late” into the activity.

It’s worth noting that the same study found that 43% of unplanned pregnancies resulted from contraception methods that were used incorrectly or inconsistently.

Contraceptive Sponge

The failure rate for the contraceptive sponge is 17.4%, meaning that out of every 100 women who use this method, about 17 will become pregnant when using the sponge.

The contraceptive sponge contains spermicide and is designed to be worn for up to 24 hours at a time, and has to be inserted before penis-in-vagina sex.

Spermicide

Studies have shown that the failure rate of spermicides can range from between 3.8% and as high as 29%, with the average rate of pregnancy over a 6-month period being about 12% (12 out of every 100 users).

According to Mayo Clinic, about 21 out of every 100 women will become pregnant within the first year when spermicides are used alone, although that number is reduced when a secondary barrier is in place (such as a condom or diaphragm.

The Rhythm Method

Also known as “natural family planning”, the rhythm method relies on tracking your ovulation cycle each month to gauge when it is “safest” to have sex while avoiding pregnancy.

It is only 75% effective when done accurately.

Emergency Contraception (Morning-After Pill)

Emergency contraception (the morning-after pill) is up to 90% effective at preventing pregnancy when taken correctly.

Effectiveness Of Birth Control By Timing Or Situation

Different situations can affect how and when your birth control works, such as what phase of your menstrual cycle you are in when you start taking it or if you recently stopped taking it.

The list below outlines a few of these scenarios.

Can I Get Pregnant While On Birth Control?

Yes, you can get pregnant while you are on birth control.

The average person does not use birth control perfectly (e.g. taking the pill every day at the same time each day), and even if you do, there is always some risk of pregnancy.

Can I Get Pregnant Even If My Partner Doesn’t Cum Inside Me?

Although pre-ejaculate (also known as precum) may contain live sperm, most people get pregnant by ejaculation during penis-vagina intercourse.

You can still get pregnant from precum during intercourse or if your partner ejaculates near your vaginal opening or while they are pulling out.

This is possible because intrepid sperm can travel all the way from your vaginal opening up to your fallopian tubes to meet an egg.

How Long Do I Have To Use Emergency Contraception?

There are two methods of emergency contraception: the “morning after” or “Plan B” pill (such as Levonelle or ellaOne), which are designed to stop ovulation, and the IUD.

Does Plan B work if you ejaculate inside the vagina?

Yes, but only if you act quickly.

You must take Levonelle within three days of having sex and ellaOne within five days to prevent pregnancy.

The earlier you take it, the better.

Likewise, the IUD has a 99% chance of preventing pregnancy if you get it inserted within five days after having sex.

How Do I Know If I’m Pregnant?

The most common signs that you are pregnant are a missed period (assuming you typically get your period), tender and swollen breasts, nausea and/or vomiting, more frequent urination, and fatigue.

If you think you may be pregnant, you should take an at-home pregnancy test or consult a medical professional.

It’s worth noting that a missed period isn’t necessarily indicative of pregnancy.

There are many reasons why your period might be late — even with a negative pregnancy test.
