Hey everybody. I am 27 and have 2 daughters and I am thinking I am pregnant again. I just had my period last week but my husband and I were not careful. For the past three days I feel bloated, so tired, and I am having hot flashes 2-3 times a day. I went to the doctor and they took blood to test my thyroid and pregnancy. I would be too early to test with a home pregnancy test. Does it sound like something other than pregnancy to anybody. I really want to shake this fatigue, I can't get anything done from being so tired.
