My period isn't until this coming up Sunday or Monday, but I've been having some cramps. I know that you can get them early, but these cramps don't seem normal to me. Sometimes when my boyfriend barely touches my stomach (where your uterus will be at) it kind of cramps more and seems sensitive. I've taken a few pregnancy test about a week ago and all but maybe 2 was negative. The other 2 were slight positive but the line disappeared after maybe 30 min after reading the light positives. What could it be?
