So I had unprotected sex 1-2 days before ovulating. Not planned we have been using the pull out method for almost a year wo accidents but my husband didn't pull out on time. Which is fine, we were planning on starting for #2 next month. Anyway, a couple days after that until now I've been having cramps and pulling sensation on my lower abdomen area. I've also been kinda moody and had bad headaches. My period is due in a week and I usually cramp a week before but this times it's being more than that and every day all day pretty much.... Could that be a sign of pregnancy?
