What was your implantation bleeding like?

Mo.

Cd 30 today out of a normal 33-34 day cycle and started spotting today. It’s pink in color and accompanied by cramping and backaches. Wondering if it’s af or IB? My breasts are still super sore (have been for 2 weeks) and usually with af as soon as I start to bleed, all my af symptoms go away so not sure what to think 🤔
