I've been on the "pill" for 6 years now. I'm currently on Orthotricyclen. About 2 1/2 weeks ago I missed 2 pills but doubled up as soon as I remembered. I followed the instructions on the packing list but its a possibilty I may be pregnant. I'm still taking the pill. I haven't taken a pregnancy test yet because I'm due to start my period in a few days. If I am pregnant, are there any possibilities of birth defects or complications due to the pill?
