Its been 7 weeks since my last period. I had a few symptoms of pregnancy early on, like fatigue and nausea, but they've gotten a little better. My problem is, my pregnancy tests are coming back negative. I have one little boy, and I've had one miscarriage, so I'm a bit freaked out. My doctor doesn't want to do a test because he's worried about the stress it might cause me. Has anyone else dealt with this? My period has never gone beyond 30 days, but the negative tests, and there has been a lot, really worry me!
