Tubal ligation and possible implantation

Brittany

Hello

I had a tubal reversal in 2016

I had gastric bypass in December 2020 which supposedly makes you very fertile.

Since I had surgery, my cycle has been regular with positive signs of ovulation.

Today I am on cycle day 16 and experiencing mild cramping off and on and brown tinged mucus pic to show.

My question is what does this look like to you? Is is possible implantation bleeding.
