okay so my son is 8 weeks & he’s been breastfeeding this whole time(with exception to the first day being supplemented because my milk wasn’t in). i stopped postpartum bleeding around 3 weeks ago. this morning i had a little blood in my underwear, but when i wiped hardly any came off so i figured it was just a fluke spotting. then, i went to the gym for the first time & while i was there i had an insane amount of blood come out & have been consistently bleeding through pads & my pants since i got home. is this normal?
