Just curious if anyone has had a similar situation... I had a miscarriage in early January and went in yesterday morning one more time for bloodwork. My hcg came back >2 so not pregnant.

This morning I took a FRER and had a vvfl. I have gotten negative tests so I know it’s not from my miscarriage. I also know I ovulated 11 days ago. My question is, could I get a negative on a quantitative blood test and the next day get a faint positive on a FRER? I took another FRER this afternoon and it was a little darker, plus I got a faint positive on a cheapie.🤔
