Hello, I had some bleeding yesterday that seemed period-like, with very minor cramping. Went to ER, and HcG level was only at 16. I’ve felt pregnant about a week, and first positive test came back 9 days ago. I’m calculated at 6 weeks, but my cycles tend to run longer and I also usually ovulate later in the month. Going in for ultrasound today and another blood test tomorrow to follow up on HcG level. I’m freaking out though!! This is my first pregnancy, and as a 27 year old in very good health, I’m really concerned that this is an unexplained possible miscarriage. Anyone have any experience with off hcg levels or period like bleeding early on???
