So I had a miscarriage a few weeks ago my hcg had dropped all the way to a 5 and than the next day I was bleeding heavy for three days and well me and my husband had sex the day before I started bleeding and than three or four times after I stopped I was still having symptoms like sore Breast headache and feeling super tired with my hcg being at five weeks ago I would assume it would have been back down to a 0 well just to see I took a test and it was positive so I’m thinking what in the work is going on here it’s not even possible for me to have gotten pregnant again all ready is it or could the drs have been wrong I’m really confused
