I'm having cramps on both sides. It feels like it's in my lower abdomen, yet by my hips almost. I've also experienced some slight shock like cramps inside my vagina (sorry if tmi). I feel dizzy and light headed almost everytime I get up too fast, and lately I've been eating way more than usual. I've taken 2 pregnancy tests, all negative. Has anyone else felt this? Could it be a possibility that I'm too early for a test to have a correct reading?
