I had a number of blood levels drawn early in my pregnancy. Around 4 weeks my levels almost doubled, then around 6 weeks my levels were very low (8,000) and obviously hadn't doubled normally between 4 and 6 weeks. The doctor thought a miscarriage was possible, but I saw the little baby and heartbeat at 6w6days at 124 bpm and again today at 8weeks 6 days at 170-180 bpm. I also had low progesterone levels so I've been on progesterone suppositories for a few weeks and will continue until 11 weeks. I was taken aback today at my appointment when my doctor suggested I do the NT scan due to my low hcg levels. She said there can be a correlation between low levels and genetic defects. She also said I could just be one of 1/3 of women whose numbers don't double properly and have a perfectly normal pregnancy. What are your thoughts on this? Anyone in a similar situation?
TIA (and sorry so wordy)
