So I went to the doctor yesterday for a peace of mind ultrasound. According to my last period I am 6weeks and 4 days. They did a transvaginal ultrasound and could see a sac but couldn’t see a baby or hear a heartbeat. The doctor said I’m either earlier than I thought or the egg stopped developing and I’m having a miscarriage. They took blood and I have to go back Monday and give blood again to see if my hcg levels are rising. Im hoping my days are just calculated wrong. I’m pretty sure the tech measure me at 5weeks 6days by my sac. Is this normal? I also have irregular periods so could that affect it?
