I had a miscarriage at 8 weeks on Easter. It took forever for my hcg to fall. I thought I was pregnant & implanted about week ago but it ended up being left over hcg causing a vfl.. I continued to test each day & the lines got lighter to the point you could barely see them. 2 nights ago I had back cramping & I think it could have been implantation. I took two tests today & they are getting brighter again. It just goes to show that you may be able ovulate with a small amount of hcg in your system & still get pregnant. I had loads of ewcm which happened a week later than my norm & I think I’m about 11-12 dpo. I’m not sure I’m pregnant but I’m staying hopeful 🤞
