Question: missed period on BCP

 sweetie8s6 - Wed Apr 27, 2005 5:35 am

I've been on birth control pills (a generic brand of Ortho Novum) for about a year and a half, and I've never missed a period during this time, but this last cycle my period did not come. I haven't missed any pills, and I've taken 2 home pregnancy tests that both came back negative - one taken a few days after my period should have started, and the other taken when it was about a week late. I've also experienced some cramping similar to what I experience during my period, except that there is no blood.

I'm wondering how accurate the pregnancy tests would be - did I take them to early? Should I still be worried about pregnancy? And also, should I be worried about the cramping but no period? How normal or abnormal is this situation?

Any and all help would be greatly appreciated!!

User avatar Hi sweetie8s6,
Pregnancy tests are fairly accurate but if there is an insufficient amount of the hormone produced during pregnacy in the urine, a blood test would be able to identify pregnancy. Missed periods do sometimes occur while taking birth control pills and if no pills were missed etc. I would be more inclined to consider that you are just having an irregular cycle. However, you may want to call your physician for an evaluation for any anomalies and to specifically rule out pregnancy.
