Results back today and progesterone has gone from 22 up to 35. Dr said to increase to 3 pessaries per day and has given me a script for stronger ones once this lot has finished.

My HCG has gone up from 908 on 9/8 to 2990 on 13/8. The Dr said this looks good, but I'm worried as it looks a good increase but it was actually FOUR days between tests... Why do they say it should double? Mines going up, slowly.
My hcg history is:

24/7 - <2
2/8 - 193
4/8 - 280 (It was the day after this I saw my Dr and she actually told me this was not a viable pregnancy, assuming I was 5-6 weeks, the numbers low and not doubling, she said it was an early miscarriage, and that this is usually due to chromosome abnormality. She said I would need a D&C and to come back in with my dh. She did have me do another BT though and thats when dh and I were shocked when she said the number had gone up, which was the next one)
7/8 - 508
9/8 - 908
13/8 - 2990

So I keep thinking about what she'd said prior, it was something along the lines of "nature weeding out the unhealthy pregnancies". Her wording was much better, but I didn't hear much after miscarriage. Obviously babies are born with 'abnormalities', and those pregnancies progress 'normally', so I don't really understand the logic. My youngest child has a developmental delay, and there was nothing within that pregancy that indicated it. This was years ago before I was diagnosed with PCOS or struggled with fertility, so I never had HCG checked or monitored back then. I just wish I had more information, what do these levels mean, what has been the experience of other women with this pattern etc. My gp is obviously limited with information I guess. I am going with an obstetrician this time but I don't see her until I'm 10 weeks... I've compared this to my experience with midwife care (my two older children were born in a birth centre setting), back then they didn't even see me until 15 weeks. I tend to thrive on information and I feel very in the dark, I do have my u/s tomorrow, and I guess I'll know more then...
