S.,
I agree you should get a blood test done thru your OBGYN, this is the only true way to find out if you are pregnant. I have always had irregular periods (ovulating maybe every 3- 6 months & then no periods in between) since age 13 & knew it would be difficult to conceive. Our 1st son was born 21 months ago & it took us 6 months to conceive (that was the first time I ovulated since we had started trying). When I took the at home pregnancy test, it came back negative but I felt similiar to your symptoms. Infact I thought I had the flu/allergies, went to the doctor who did bloodwork & discovered I was 8 weeks pregnant. After my son was born, my cycle was still irregular & we miscarried 7 months after he was born (never even knew we were pregnant until I started clotting etc). Now we are having a scheduled c-section for our daughter this friday the 26th. It only took us 1 month to conceive, but it was during my period.
My sister never tested positive for pregnancy during her entire 9 months & I knew another lady who had her regular cycle the entire 9 months. My other friend spent $50,000 to try & conceive until they ran out of money. Within 4 months they got pregnant naturally & had twin boys 7 months later. Everyone's body is totally different. It can't hurt to get it checked by the doctor & ease your mind. Good luck & keep us posted. S.
