Period due in nine days...

Hi all so AF is due in nine days and I got some cramping on the weekend An yesterday morning. I had spotting on Saturday on an off. Its pink An brown.. . annnd then lastnight out of nowhere had a gush (I know I'm sorry lol) of pinkish red discharge. It was there for about thirty minutes an is gone An my normal discharge is back.. my partner and I have been TTC. But I had an early miscarriage (5w5d) about a month ago now. So we weren't sure if it could even happen. I usually ovulate earlier than I am suppose to as well. As I always have, idk why.. I have a 30-31 day cycle an I still Ovulate early every month. When I last got pregnant it was right after my period.

Could it be implantation..? Or...?
