antibiotics do affect your pill and if i was you id go have another test done at a chemist to be on the safe side if its negative again and your period still not appear go and see your gp who will be able to advise you in confidence.your body can play tricks on you if your very worked up try to relax easier said than done i know but you might just find your period will come and things will be ok.good luck
The antibiotics had NOTHING to do with any pregnancy risk. However, only taking the pill four days out of the month certainly does. You have to take it every single day at about the same time in order for it to prevent ovulation, i.e. be effective, so you might as well not have taken it at all. Why did you discontinue the pill if you were still sexually active and trying to prevent pregnancy?
In any case, you probably aren't pregnant... but if you don't get your period soon, I'd see your doctor to be sure. While you're there, talk to your doctor about a reliable form of birth control - if you feel you can't take the pill every day, then use another method. But only taking the pill when you have sex is pointless.
I agree with monkeyflower its totally pointless only taking it on those days because it even says your only fully protected when you take it on the first day of your period, and also its to stop ovulation not the sperm reaching the egg!
So I think it could be more than likely you could be given the odds that u was having unprotected sex. I think take another test (early morning sample and a preg test with the pink ink gives better results so Ive seen tested on peeonastick.com) and if nothing maybe a wait a little more see if you get more symptoms.
Symptoms can ware off and come back etc thats what happed to me when I was preg
Anyway hope you get the answer u want and let us know the result.......
Thanks to everyone for their comments,i do blame myself for not taking the pill responsably, I know now, but I have to go from here..any other advise is greatfully acknowleged...thanks..and I will let you know what happens
I'm sorry, I really didn't mean to chew you out. I mainly just wanted to point out that blaming antibiotics (btw, newer, better studies have shown that aside from rifampin, antibiotics do not interfere with the pill anyway) was sort of pointless when you were having unprotected sex to begin with.
I really wouldn't stress out too much; your period may just be off schedule from taking your pill so irregularly. If you don't get your period in a few days, see your doctor.
Antibiotics still affect BCP's. Even though there are some studies that say other wise there are more studies that say it does. I know several people who took the pill everday, same time, etc and became pregnant because they took an antibiotic. But also not taking the pill responsibly could lead to pregnancy. Schedule a drs appt and get a blood test if you really want to know, and then get another form of BC.
