I've taken antibiotics 3 times over the course of 1 month.
First, a z-pack for a sinus infection.
1-2 weeks after I finished the z-pack, I was given a 10 day supply of antibiotics to finish off the infection (I assume it didn't affect my birth control because I still got my period on time.)
My period is due this week, (actually, it should be here today), but I just started bactrim on Monday (6 pills), could that have delayed my period when combined with all of the other antibiotics I've taken? My boyfriend and I did have sex while I was on the antibiotic, unprotected, but still used the "pull-out method"...I'm starting to get worried. Please help.

You need to take a home pregnancy test. Antibiotics can cause your birth control to be ineffective. Pull out method DOES NOT WORK, precum has tons of sperm and it only takes one. Believe me, I know and I know others who have gotten pregnant using withdrawl.
Anyway, take a test so you plan what the next step will be for you and in the future, use condoms while on antibiotics and for another week after.

good luck

Thank you. I work at a doctor's office and when I had my urine tested for a UTI, I also took a pregnancy test and it was negative. Was that too soon to tell?

Depends when you took the test and when your period was due.

My period usually comes toward the end of the week, so really it's due today. And I took the test on Monday.

Well, then you should wait for a week and if it still hasn't come then by that time it should register on a urine test. You can get the kind that you can test 5 days early as well. But since you haven't missed your period yet you can relax and if it's not here by Monday, take a home test.

Okay, thank you! I'm trying not to stress over it, but I also can't get my mind off of it. I called my doctor to ask her about it, too, but she has yet to call me back.
I appreciate your answers though, thanks a lot.
