TMI: For moms who have had IB with BFP

Hey ladies! Here’s my story...

So I am currently 7 DPO according to the app and my next period is expected on Jan. 21... yesterday I had a slight tint of pink on the toilet paper when I wiped, then today I had this (see picture)... did any of you have IB that led to BFP with this ? I did have mild cramping two days ago but no other symptoms that I have recognized.

Also, I did have a miscarriage in July and with that pregnancy I did have IB at 10 DPO. Hoping this is my rainbow baby 🥰 thanks for all of your help ! Keep posting I love reading your stories!
