Arrrrghh!

I've had 3 periods since giving birth 4 months ago and they've all been different. The first time it was super heavy on the first day, tapered off the 2nd and 3rd days and all but disappeared on the 4th but returned with a vengeance on the 5th. Mind you, they normal last 3-4days. Second was lighter and manageable for 3days, then got heavier and went on for 4 more days. This time, I started off spotting for a day then it got super heavy and it's now day 3 and I've soaked through pad and clothing twice. Plus I'm cramping, another thing that's unusual. I'm miserable and don't even wanna go outside because i'm afraid to get out of the car, going from sitting to standing causes that all too familiar gush but this time it's coming down my legs. Doc said everything's fine and will return to normal, I really hope it does and soon. Did I mention, I was irregular before? or that it's also my birthday? 😒😔😭
