Bleeding after giving birth

Hello mommies! Gusto ko lang po sana mag ask if normal to or may iba pang naka experience. I gave birth last 2nd week of June. After 2 months nagka period na ko. Ok naman tumaggal sya ng one week. Then 1 week after period ko. My partner and I had sex kahapon lang. After sex, dinugo ako and may konting pain akong naramdaman during sex namin. Until now my bleeding parin ako pero no pain naman po sa private part ko. Bakit po kaya ganun? Normal ba? May naka experience din po ba neto sa inyo? Thank you in advance sa mga sasagot po. #Firsttimemom #respect_post
