Question
Does Bactrim affect Lutera birthcontrol?? Because I've been to a couple Pharmacy and some say it effects it and some says it doesn't. I really need to know because I've already had unprotected sex and I wanted to know am I safe from getting pregnant. I been on it for a month and a week but I took Bactrim for two days with the first pack. When it was time for a period it came on time and last for 5days and thats normal.I'm really scared and really need to know am I safe.I'm on the 5 day on my second pack and today is the first time my boyfriend ejaculated in me. I take my pills on time every day..if you can please write back asap thanks. Sincerly,Very Worried.

Answer
Hi Symone,

I'm not sure how much Bactrim affects Lutera but there is no such thing as "protected sex"
This is something that is a myth. All birth control methods are not 100% safe from pregnancy.
So even if you used the pill correctly and on time, you can still be pregnant.
I would contact a pregnancy resource center near you to find out when you could take the free pregnancy test. http://www.optionline.org or call 1-800-395-HELP.
