Honey - so sorry that you are still going through the mill. I take it that you are under a consultant? - if so you will need to go back to him if you do miscarry, he will want to see you afterwards.
You sound very hung up on your results and blood levels, which I can fully understand - but do try not to be so anxious about every change, or try to self-diagnose. As you say, everyone is different, and you need to try to relieve your anxiety levels, it may not be helping.
I'm with you in spirit, I know what a horrid time this is - keep us informed.
