My last period started July 16 and ended July 19. I had unprotected sex July 27th. My calendar said I ovulated on July 30. I noticed on Monday, August 6 I had very dull cramps. They weren’t painful but I knew they were there. The cramps will last all day but would come and go. As of today Sunday, August 12. I’m still having dull cramps. My period is due August 13 (tomorrow). I normally have cramps 2 or 3 days before my period starts, they’re normally extremely painful, and I always have to take Advil’s once they get here to stop the pain, but these cramps felt very different. There extremely dull, not painful ,but feels like their coming from my uterus. My cycle is 28 days long and some times my period is late one day or early. Do think I could be pregnant? If so, when should I take a test? Right now I am 13 days past ovulating. I also have no other Symbian’s but dull cramping a week before my period.
