I was taking birth control pills august through October on time everyday to regulate my cyces and taking the pills regulated my cycles while on the pill and off. I been trying to conceive my first baby since I got off. My last 3 cycles were november 20-24, December 18-22, January was suppose to come on the 15th but I am now 3 days late. I feel like a period is not coming. I have been feeling nausea on and off, cramps that come and go but no period. My fiancé is taking naps all of a sudden, and eating sweets. I dont know if that has something to do with me. But we have been trying and my online ovulation tells me I ovulated January 1st and other days around there. So we had sex December 23, 24, 25, 27, 29 and January 1, 2, 3. Can someone tell me if I may be pregnant or am I going back to a irregular cycle?
