I am 10 weeks pregnant today. I verified my pregnancy by going to ER when i was around 6 weeks. I was told they couldn't see the baby on the ultrasound because it was still early and because i have uterine fibroids (which I never knew)and they didn't look for a heartbeat I don't think. I found a doctor and had an appointment when I was 8 weeks and 2 days. She didn't let me hear a heartbeat or do a sonogram. She said I only get 2 sonograms so I have to wait until 12 weeks. I'm worried that I don't know my baby's progress because I've had a little spottting off and on since my last visit but the doctor told me not to worry if I'm not in pain or filling up a pad. Idk what I should do bc I'm still worried, this is my first baby.
