R.C.
Progesterone above 12 at 4 weeks gestation is considered very normal. Please ask them to repeat your progesterone and quantitative hcg in a few days to see if both are rising (48-72 hours is typical). If both are rising appropriately, I'd encourage you to not to use the progesterone suppositories as they would not be necessary. I don't think your nausea, headaches and difficult labor are related to your use of progesterone. I hope this pregnancy is much more enjoyable. Congrats and best wishes! Nurse Midwife Mom of 3
