It likely isn't your period, but a restart of some lochia.
I had the same thing happen with my first and my OB confirmed that at 6ww pp anything happening while ebf is most likely lochia. She also did my pelvivc exam at that time and told me it was lochia.
I'll hit 6 weeks since my c section on Thursday. I haven't really stopped having lochia since. Some days it's super light and some days it's a bit heavier.
