Advice please? Implantation bleeding? TMI pic

Linda

My period started the 8th and according to the app I was suppose to ovulate on the 22nd. I believe I actually ovulated earlier (19th or 20th). We BD on the 15th and the 19th and Wednesday night (24th) I started spotting. It started off a brownish pinkish color then got lighter. It lasted about 2 days, it wasn’t constant the whole 2 days either, usually when I wiped and there was a little in my underwear. I’ve never had ovulation spotting before and AF is still 8 days away. I took this pic on the Jan26, it was the last of the spotting. Could it be implantation bleeding?
