I got married on November 3rd and was on a medication for 2 weeks before my wedding called aygestin (it pushes off the period.) The plan was that if there's successful penetration the night of my wedding, I will stop taking the medication, and will get my period 3 days later. I'm Jewish, and once I get my period, I can't have contact with my husband until after immersion after 7 clean days once the bleeding stopped. The next time I was with my husband was on November 20th. I'm currently 5 months pregnant, and I realized that they asked for my last period, which I have the date for, but it wasn't a natural period. It was also a lighter flow.
According to the doctor's estimated due date, I became pregnant when I was not able to be with my husband.
Is it possible that I got pregnant the night of my wedding, and that I got a very light period because I was laready pregnant?
