I had some spotting a couple weeks ago but my hcg has been going up and very quickly. I have had 3 ultrasounds. First one they seen nothing 2nd one they seen fluid in my uterus and 3rd one they seen something In my uterus that was measuring 5 weeks. I should almost be 8 weeks according to my last period but going off what they gave me I am only 6 weeks. I have another ultrasound scheduled for next week. I just don’t know how I found out so early with a home pregnancy test? Why my hcg is rising so quickly and why they can’t see anything? Has anyone had this happen. They were worried about ectopic or miscarriage but again my hcg is quadrupling in 2 days?
