Hi, congrats! Just to share, I had 2 miscarriages before at 18weeks & 8 weeks. I am currently 32weeks pregnant. During my first trimester I had brown spotting. I saw my gynae for first appt when I was about 6-7 weeks pregnant. No point going too early as the gynae will do urine test & scan (which you might end up see nothing as it's still early).
My gynae gave me dydrogesterone tables & progesterone injection (once every 1-2 weeks apart) to stabilize my pregnancy.
At the meantime, try to relax. Don't stress. Just try to rest more!
