Please help... Just worried what to expect

My LmP was 26th april, and i have missed my period, i had my blood work done today at 4 weeks 3 days my bhcg is 137.5

My fasting blood glucose level are also high 130

And my t3 and t4 are normal but my tsh level is 6 i. E also high

Last time also i got positive on home pregnancy test but periods came after 3 days. Doctor says that i am getting fake positive on hpt so todo blood work for bhcg.

But now i am really worried is my bhcg levels too low ???

Does anyone have successful pregnancy with low bhcg???

I am really sorry if i have posted it in wrong group
