Hi, I had taken ipill within 40 hours after being together unprotected. was feeling nauseous for 10 days. and i started bleeding (without much pain like regular periods) after from the 11th day for 5-6 days. again now after 3 weeks i feel bit nauseous. i have not resumed my period post my pregnancy delivery (1 year). I am still breast feeding once a day. I want to know whether i need to do a pregnancy test now? or the nauseousness and tiredness is due to ipill effect and need not worry. Please guide.
