Should I be worried that I am pregnant????? ( read )?

Last week I had unprotected sex. He pulled it out before he ejacualted. I AM on the pill (seasonique) but i recently changed the time I take it from 5p.m. to 9:00 pm. And then a day and a half later I purchased Plan B (the morning after pill) cause I was so worried.and i took that at the appropriate times.. but i was on antibiotics this whole week.(zithromax to be exact) for an upper respiratory infection..and dont know if that would cancel any of that out?
What do you think??

Answer:
You’re likely to get pregnant only 2 days a month, so first of all that's like a 1/15 chance you had sex at a time when it was even possible. You are also on the pill and he pulled out. I know that antibiotics can make the pill less effective but Plan B works in the first 72 hours so you really have nothing to worry about. You're not pregnant so just put your mind at ease. If you continue to worry about it, wait another 2 weeks and take a test, when it comes up negative you'll feel a lot better. :o)

Answer:
sounds like you are worrying too much. you’ve too many odds in your favor that you are NOT pregnant. the pill is less effective when taking antibiotics, howevever Plan B should have worked if you had conceived. I wouldn't worry about it. If you end up being late for your period, take a test, but I doubt you are pregnant with the facts you’ve shared.
