I had unprotected sex 3 and 7 days AFTER my ovulation. My period is 2 days late but I feel like it's too soon to feel symptoms of pregnancy. I have read there is a very low chance of pregnancy after ovulation and before your period. But I'm not sure. Lately my period has been a little screwy. I woke up this morning about 15 days after ovulation (2 days late) with the feeling in my stomach that I havent eaten in a while. I had energy but its felt like this all week. Could I just be over thinking things? Or is there a possibility?
