Implantation bleeding

Kristen

Been TTC baby #1 for almost a year. I have an irregular cycle so ovulation days are sometimes hard to pinpoint even with the test strips. My cycle is usually 30-35 days. Tomorrow is day 35. Earlier today I saw some pink on the TP when I wiped. This has never happened before. It was just that one time and haven’t had any signs of AF since. Wondering if it’s implantation bleeding. Thoughts?
