I just started taking BC, I counted my days wrong, I had unprotected sex on the sixth day of taking Trinessa, do I have a chance of becoming pregnant?
Any oral contraceptive has an approximate 9-10% failure rate when taken correctly, so to answer your question, yes you could be pregnant. Oral contraceptives do not offer immediate protection. You did not indicate if you were menstruating when you started your birth control, or if you did a Sunday start. If you started taking a oral contraceptive at least 5 days after the start of your period then you are protected the following day, however if you started the Sunday after taking the pill then you will be unprotected for at least a minimum of a week. Not only that but a oral contraceptive must be taken at the same time of the day, every day in order to be more effective. Taking it at different intervals of time every day will yield its potency at preventing pregnancy. Most doctors or gynecologist will advise waiting until the next start of your cycle until you can have unprotected sex, or a month after starting the pill if you did not start taking the pill at least 5 days from the start of your period.It is always best advised to follow that information since not all women respond to hormones the same, and oral contraceptives, again, have a 9-10% fail rate, which in comparison to just condoms that have a 14-15% fail rate should be used with caution. If you are going to take a oral contraceptive I would advise using condoms as well when ever having sex if you are not taking them correctly. If you are also worried about pregnancy then Plan B is available at some pharmacies (depending on the pharmacist) but is most effective at least 24-72 hours after sex. After that time frame the effects are drastically dwindled.
