Implantation bleeding?

Whitney

Hi all. After a battle with cervical cancer, being left with only one ovary and a small part of my cervix we got the ok to start trying for #2. With #1 I didn’t have IB, but yesterday I think I had some that I only noticed when wiping (happy to share a pic). AF is due on the 1st- I took an early detection test today and negative. Did anyone get negatives up until AF was due or late? I’m trying not to get my hopes up but it’s so hard not to!!!
