My daughter is on an antibiotic for her acne called Doxycycline Hyclate. She is also on a birth control pill called Karivar.  Does she have a good chance of getting pregnant if her partner did not use a condom?  I Also calculated when she would be ovalating and it was the day she had intercourse.
Hello! Thanks for your query. Doxycycline reduces the effect of the pill. Pregnancy and breakthrough bleeding can occur. If she was ovulating in the day of unprotected intercourse, chances for pregnancy are larger. Additional contraception should be used for the first month from using doxycycline. TAKE CARE
