So I had a loss January 1. I bled for 6 days. My ob said it wasn’t necessary for to get my betas after, which is fine. So I was using the cheap strips to see when it got to zero, or undetectable. I got a negative last night. And I’m pretty sure this is a faint line from tonight. Has anyone gotten pregnant after a miscarriage without having a period? I got a positive ovulation around the 16th. I would be 6-7 dpo. These are early detection.

Top is last night. Bottom is the faint shadow from today.
