Postpartum irregular menstration

Hi👋, I'm a not breastfeeding mom with a 7 months old baby. Now I'm wondering if my menstration is still normal? Here's the story; I was giving birth with my first child last August 17, 2020. As all moms experienced the bleeding start right after the child birth and it ends after 3 weeks. I got my menstration back on November 1, 2020 and it lasted for a week which is my normal menstration length. December came and It happened the same thing. But when January 2021, there's no menstration happen until March 28, 2021. So I got my period back on March 29, 2021 until now and I'm getting worried coz its 20 days already and the bleeding doesn't seem to end, its still heavy. If anyone have the same thing or have any knowledge about this kind of situation please comment? I badly need an answer. Thank you. #1stimemom #pleasehelp #firstbaby #baby #respect
