EBF and period

Rachel
I'm EBF my 8 week old. She doesn't take a bottle...so its only me feeding her all the time. I stopped pp bleeding around 5 weeks pp, but I think I started my period. I thought when you're BF, you're not supposed to get your period? I know every woman is different, but I'm kind of concerned that being on my period will affect my milk supply? Anyone have the same experience?
