I just had a second chemical pregnancy on 12/20 after having one on 11/6. My doctor put me on progesterone after I thought I miscarried again because my levels went up so he thought I could still be pregnant. However after getting a third test on 12/26, my levels went from 44 on 12/21 to 5 on 12/26 meaning I really did have a miscarriage. He said to stop the progesterone but start it again as soon as I get another positive hpt and to schedule an ultrasound at 6 weeks as opposed to the traditional 8 weeks so he can see how things are progressing. I am planning on waiting for a period or two before trying to conceive again. The second pregnancy was unplanned and extremely stressful since I had just gone through a miscarriage and was terrified of another. I am typically pretty good about tracking my ovulation and so I am wondering if I should just start the progesterone after I ovulate (after a cycle( to be sure my body has enough progesterone before it is too late and I lose a 3rd pregnancy. Has anyone else done that? Has it helped them?
