I'm so confused..

Jordan • Two miracle babies 👧👦 two angel babies 👼👼now trying to conceive our 🌈🌈🌈

Has this happened to anyone? So my last blood draw was friday morning and it had gone from 90 to 67. So I was told I'm having a miscarriage. I had a ultrasound Thursday that confirmed I'm not having a ectopic. So out of curiosity I took a text this morning to see if my levels were low enough to get a negative because I've been bleeding a good bit. So heres where the confusing part comes in. When I took a test the morning I got my blood work back at 90 the test line was still so faint, alot fainter than this one. But this morning it looks like this. Has anyone had this happen? What could be going on???
