Same thing happened to me!! Completely normal
Same thing is currently happening to me as well but started once I started going back to the gym lifting weights and was a little bit worried myself
Mine stopped 2 weeks post partum and started again 4 weeks post partum. Went to chat to a doctor they told me it was my period coming early eventhough I’m breastfeeding so could be period? X
Mine did the same, lasted a week or so and stopped again - no bleeding now 8 weeks PP, I wondered if it was my period … but I don’t think it was x
