I just posted a question about my nipples being sore and enlarged along with the areola.. and a few days ago i had terrible cramps, so bad that i couldnt get up off the floor for 15 minutes. I have never had cramps before. I usually have no signs before i start,, and i'm late,,, i took a pregnancy test a week ago but it was negative. I'm only a few days late now. Is it common for people to get cramps that bad? And if it is unusual for me to have any premenstrual symptoms then what is this? should i see the doctor or does it sound like its normal?
