Spotting 9 weeks/vanishing twin

Haley

I started spotting very lightly at 8+1, went to get an ultrasound and they discovered there were two sacs, but one was empty. The other had a healthy little baby, strong heartbeat and all. My dr didn’t really seem too concerned with the spotting, suggested maybe it was my body trying to decide what was going on with the empty sac. He prescribed progesterone and it had since stopped until today. I’m 9+2 now and am worried 😢 has anyone had a similar experience and can offer some positive feedback or advice to help ease my mind?!
