I'm on Loestrin 24 but was on antibiotics for a few days, and my boyfriend and I had unprotected sex. He read up on what antibiotics causes birth control to be less effective, but we're still a bit paranoid and are considering the morning after pill. Due to my working schedule it won't be possible for a few days to get a hold of my doctor.

Why did your boyfriend have to find that out? You should be learning all you can about a medication you take. Or come here and ask when you have a med prescribed, all you need to know about it. You can take plan b when you're on the pill, but be aware its going to really mess your system up. Here is some info I like to give on the pill. Oh and all your docs need to know what medications you are on. If the dr who prescribed the antibiotic had known you were on the pill, he could have told you to use back up birth control. Birth Control pills work 3 ways. They prevent ovulation. They decrease the lining of the uterus, and they thicken the mucous at the cervix.
This means that if you take your pill every day at roughly the same time, you will not get pregnant. There are some medications that decrease the ability of the pill to work. One of them is antibiotics, so that if you’re on them you should use a backup method of birth control.
You will not get pregnant when you are on the inactive pills. YOU DO NOT OVULATE WHEN ON THE PILL.
You may have a very light or even no period from time to time because of the decrease in uterine lining.
You do not ever need to take plan B. The only reason for condoms when on the pills is to prevent STDS. Except of course in this instance.
If you forget a pill your chances of getting pregnant increase slightly. The more pills your forget, the more your chance of pregnancy.
When first starting the pill you need to use back up birthcontrol for at least the first week. After you start the pill, when you have your period has nothing to do with taking the pill. You just keep taking them one pack after the other. You do not stop them if you start spotting, you do not stop them if you don’t have a period, bleeding has nothing at all to do with when you take your pills, once you’ve started them.
