I missed 2 birth control pills in a row, which resulted in taking 2 pills a day for 2 days as directed. During this time, I had unprotected sex (a couple of times). Recently, i have been fatigue and getting headaches (something unusual for me). I am now 3 days late with my period. I have been on the pill for 6 years so I am aware of what is normal for my body. (Also, I started off with the pill to regulate my periods from a history of ovarian cyst instead of avoiding my chances of pregnancy). Am I pregnant?
