Good night! I have a question: if I took a doxycycline 50 mg yesterday around 4pm, for how long will it stay in my system? I m also taking a birth control (every day, same time)and tonight I had sex with my husband and he came in. Any chances of pregnancy? Thank you!
hello user.dont worry.birth control pill provide 99 percent protection..doxycycline does not decrease the effectiveness of birth control pill.thanks.
