Last month I found out 4 days b4 my period that I was pregnant the few days later a test said that I wasn't, I went for blood tests and they came back borderline, so went for more and they confirmed that I was no longer pregnant :( everyone said it must have been a chemical pregnancy, I am now 8 days late on my next period, I have done 2 tests both come back - ! Am just confused, not sure if it's normal to be late after a chemical pregnancy or if I could actually be pregnant but tests just not showing it yet? I have no pregnancy signs, only thing different is I keep getting headaches :( please help?
