I had sex for the first time on may 15 , 16 and 18th. I got my last period on may 3rd. I have a small cycle of usually 2.3 to 3 weeks, so I was expecting mine on 24 or 25th. but I have still not received mine.

we used male condoms. and also one thing was wierd that I had sever low back pain on 20 and 21st that I had to midol to get to bed.

am I pregnant? or am I late because it was my first time? also.. usually I would PMS real bad and get into all kinds of arguments, but not this time..

please help..

I and most of the girls I know had really late periods after our first time.
Think about it, surging hormones; those same hormones that regulate your period, as well as the stress of first time sex.
Don't worry about it

My period was regular at age 9 (poor me!) and after the first few times I had sex my period was weird... however, it got back into a regular routine again even though I have sex regularly. Some women have very regular periods on there frist times....

Every woman is different!

If the condom was on during the entire act of intercourse and did not break, you have a 0.1% chance of being pregnant... that's pretty much non-exsistant!!

As for the PMS thing... when I was pregnant I was sure my period was on the way, and was sure it was going to be double hard. I screamed, cried and threw things... and I'm not really the crying type! I would describe my pregnancy as 9 months of PMS

Relax and wait for a while for your period, if you do not get it in two weeks, take a pregnancy test and go to the doctor.

Best of luck!

Thankyou very much.. will keep you updated.. still..nothing...

I had the same thing happen. After my first time, I missed my next period. I freaked out! And I was afraid to even get a test to find out for sure. I feel silly looking back. It is smart and easy to just run to the store and pick up a test. But don't rush yourself. Do the test properly. They usually give you two. The way I've used them in the past: I'll use the first immediately because I REALLY want to know. Then the second one, I'll use the way you're supposed to (usually certain day/time-frame, and first pee of the day), so I get more accurate results. That, too, might be silly, but I still like doing it that way. I did it that way for my last 2 pregnancies.

Maybe take a home pregnancy test. It might just set your mind at ease. They are very easy to use and relatively inexpensive. You will know in minutes.
Good luck
