I am currently 9weeks post partum and according to glow I ovulated on the 24th of this month but I’m starting to wonder if I ovulated earlier this month like say the 19th because we had sex on the 15th and the 18th and starting last night I started lightly spotting it was light pink this morning it was pinkish red and now it is light pink again. My period is expected on the 6th according to my app but if I ovulated on the 19th instead it would be a few days earlier. Could this be implantation bleeding?
