I went in to the walk in clinic a couple days ago because I was bleeding and had a lot of pain. I've also had bad morning sickness, and cramping like I'm getting my period. They did an exam drew blood, and did an ultrasound. My HCG level was 11567.5 when I went in for my ultrasound the lady said my levels are really high for 5.5 weeks, but we only seen a sac and a Yok sac? No baby, why would my hcg level be so high if we can't see anything? Has this happened to anyone else and they had a healthy pregnancy I'm so nervous?
