I'm 7 weeks postpartum and got the go ahead from my doctor to resume all activities last week. Wednesday i decided to start working out, did some yoga and light weight lifting then decided to do a brief HIIT workout, then later that day I went for a fairly long walk. The next day I started bleeding (my pp bleeding stopped at 4.5 weeks), I thought it was just from overdoing it the day before but I'm still bleeding today, could this be my period returning (please say no)? I'm EBF but little guy has been sleeping for fairly long stretches at night lately.
