Ok I'm 7 months post partum and I'm pretty sure I ovulated on the 5th or 6th. Then im pretty sure I had "back " cramps about 7-8 days later so I'm convinced that with the fatigue breast tenderness moodiness food sensitivity constipation ect I am pregnant. But my tests are coming back negative. Now I havent had a cycle yet since my son because I am breastfeeding. But my tests for all three of my previous children I think were positive by now. I feel like I'm going crazy.
