So I had unprotected sex with an ex partner on the 24th August and since the 30th August I've had daily nausea. According to my flo app I wouldnt have ovulated till 29th August and im due on my period on the 13th September. I've got tender boobs and a bit of acne which I would normally get before I'm on and a bit of nausea but nothing to this extent which as I said before has been daily. I've done 2 of the early pregnancy tests which have come back as negative
