Advice please

Hello beautiful mommas. My daughter was a rainbow and this group was so amazing. Now I’m afraid I might be in need of your advice again. My previous miscarriage I started bleeding before I knew anything was wrong and things progressed on their own naturally.

I’m pregnant again after having my rainbow girl. I went in for an ultrasound when I should have been 7w3ds. I had gotten a positive home test on 10/13 and waited on purpose to know that by then baby should have had a heartbeat.

I wasn’t shown the screen but overhead the tech say there was just the gestational sac to measure and it was 6w3ds. I held it together while they finished out the ultrasound and waited over an hour to talk to my doctor. By the time she got in the room I bursted into tears saying there was no heartbeat was there.

She said not to throw in the towel yet. We are doing bloods again tomorrow then a third time Monday and then repeat ultrasound next Friday.

I just don’t see how it can add up with when I got my positive vs being only 6 wks so in mentally preparing for the worst.

Given there’s been no bleeding yet and no issues and my symptoms are still here I’m going to assume I may need a d&c or the medication to bring about the loss.

I’m not sure which is the right route to go should it come to that. Any input would be greatly appreciated.
