I’m currently 43 days without a period, I’m usually 33 days roughly. I received 2 positive tests a few days ago with mild aching in pelvis like period cramps on and off and then a few days later I received a few negative tests. What is going on? My breasts feel heavier/lumpier than normal and can be quite tender at times and I have been feeling nauseous occasionally. Could I have had a false positive??
