Hi ladies. So I went for an ultrasound at 5weeks5days pregnant. Saw a little baby/sac in my uterus with a flickering heartbeat. Fast forward to 6weeks 4 days , I felt a gush and started bleeding with cramps. The bleeding wasn’t crazy heavy, kinda like a light period. next day went to dr. And the baby got so big measuring 6weeks 5 days. Sadly they said they couldn’t see a heartbeat. So i went home still bled, passed one big clot and the bleeding stopped. I’m testing to see my hcg dropping but I feel my test are dark? I also feel pregnant. So nauseous, starving, and have insomnia. This was my 4th pregnancy, I have two boys. How long does it take to lighten?
