2 months pp, multiple “periods” after lochia ?

Denee

Okay guys I’m kinda freaking out. I stopped bleeding from birth around 5 weeks then began bleeding for about a week heavily about 4 days later. I told my doctor she said it was probably my period. But now at week 8 I’m bleeding heavily again?? It started after a few days of sex but I mean it’s not spotting, it’s like my period is on heavily again. I’ve emailed my doctor but she hasn’t gotten back to me. Just wondering if any of you ladies have experienced this?
