Hey, need some advice.. so this month I'm 7 days late for my monthly. Last month I was also late but then a few days later I started to bleed. I done a test that month which were coming back negative. I'm under active and taking levothyroxine, I've spoken to the doctor and she said to redo a test which I will but I said I know I'm not as we havent even done the deed this month. So would you said I need to have another blood test to review my levels or what?? I'm so worried I wont be able to have any more babies now and it's the end of line for me. She said after 3 months of not have periods I'll go for a scan and what not but I dunno
