Hello! I am lost and thought I would join and see if anyone had advice. I am 7 days late to start my period and have taken 4 tests all negative. My ovaries are cramping from time to time especially at night. I have fuzzy brain and can't think straight, and I get a pinching sensations in my belly from time to time. Don't know what is going on with me. I'm always regular, I usually get my period every 26-28 days. Not on the pill, not trying to get pregnant but also not not trying. What is going on with me, getting worried. Any advice?
