Ive been on the pill for two years now with no problems. Last week I had slight cervical cramps like the kind I get when im on my period, I went to the doctor, ran some tests, preg test negative, bacterial negative, she said it was a very low chance of pregnancy since I'm was too early to test. I was really cranky on friday, tired on saturday, the cramps started that wednesday. Is this normal? I 31 and ive never experienced this.
