I have not had my period.. and I’m 18 DPO. I tested but it was negative. Has anyone had to test multiples times? I have this cramping in my right lower region by ovary. I never miss my period EVER. And I have shortness of breath, back pain, gas, heartburn, etc. and it doesn’t even feel like my period is coming any time soon. Usually my breast are sore before pms.. not sore right now. Nipple tenderness sometimes. I’m so confused. I have no bleeding but I just think this is coincidental. The first month I try, then everything is all weird.
