I was sterilised just under 6 months ago after my 4 the c section and although I'm still breast feeding my period did return which is unusual for me. However I can not remember when my last period was I've taken a test and although it's negative I still feel pregnant. Nausea slight cramping dizziness and heart burn from hell! Another big tell tale for me is that I'm off coffee which is highly unusual. Anyone any thoughts ? I can say with certainty it has been more than 21 days since my last period but I honestly can't remember past that but surely if I was the test would then show as positive???
