Hi I'm 18 I haven't had my period for 3 months and well I took a pregnancy test and they were all negative but I have all the symptoms of pregnancy my breast have gotten larger I'm eating and having morning sickness. I just don't know what's wrong with me I went to the doc she just gave me bcp to try to regulate my period but its not working what could be wrong? Could I be pregnant?

I assume she did a pregnancy test before giving you're the pills? If it was just a urine test, it probably would have been wise to do a blood test to know for sure. How long have you been using the birth control pills? I'd check back with your doctor, be sure she knows the symptoms you are still having. Birth control pills may take a few cycles to help regulate periods, but your period has actually been absent so another choice might be made instead.
