Hello. I have 2 healthy children, my very first pregnancy was ectopic (required a tube being severed) I have had 2 miscarriages in the last few years. This pregnancy I took an at home test 5 days before my missed period and it was positive. Went for blood work and my hcg was at 68. My Dr said I was just a minute pregnant. Lol. Went back 48 hours later and it was at 2200. That is so much more than doubling. I just dont understand what that means.
