My last period was January 17th and according to mymonthylycycles.com I ovulated on Feb. 3rd and I've noticed that I've had some breast soreness around the sides and yesterday while I was taking a walk I had what felt like cramping in my uterus. My period is not due until the 17th of this month and I had unprotected sex on the 3rd as well as a few days before that. We usually use the \"withdrawal\" method since we have an almost 9 year old and a 7 year old.. I've been on bc before but not for a very long time.. anyway, I was wondering if this could be early PMS or if I'm pregnant.. I know that it's way too early to test.

Thanks for any help!!
