Any one have answers?

I had a baby about 6 weeks ago 7 weeks on Friday. I stopped bleeding about week ago fully. Been having sex. During the beginning of the week of stopping bleeding I had this discharge that was like a mucus plug it was so weird yellow pinkish and really jelly it was a big glob. After that, My discharge had turned white and thick and got kind of dry yesterday. Yesterday night I had a gush of super watery brown discharge and it lasted till earlier today and now has stopped. Was this implantation bleeding? Or left over blood from birth and having sex? Has anyone else experienced this?
