I am pregnant, is it twins and are my thyroid levels normal?

Hi doctor I am 5 weeks 4 days pregnant. Please let me know if I need to increase thyroid dosage I am currently taking 50. Also the hcg levels look elevated to me is there a possibility of twins. Or does that indicate a singleton pregnancy? I am just wondering if it is multiples as it looks high to me but maybe it’s normal for a single.

I’m 3 weeks pregnant and my hcg level only went up 139mIU, please advice?

I’m 3 weeks pregnant and my hch (hcg) level only went up 139mIU I need 69 hours. I was in the emergency room with crams after intercourse and I was spotting prior to the visit. They said I was pregnant and a few days later my hcg levels went from 200 to 514. 68 hours after the last blood work was done, they are at 615.
