question: It has been five weeks since my last period on august 2(last day of period). In between, we had intercourse around ovulation time and then after some days I started feeling nausea and abdominal cramps. No implantation bleeding. Now i have missed my period (expected date was 31st august) but both pregnancy test have come out negative. my second test today (september 4) showed a barely visible positive line but that was after a few hours of testing. Could I still be pregnant? We have been trying to concieve since January 2015 and i am 33 yrs old now.
