Extremely heavy since giving birth in April

Al

My periods have always been somewhat heavy and very painful. I was on seasonal BC until we decided to try for a baby. We were very successful with only two cycles off the pill. She was early due to complications with me so we decided to get my tubes tied as we each had a son by a previous marriage. I got my first period and it was so so so heavy, second still the same so on and so on. I’m going through the super plus tampons within an hr 2 if I’m lucky. Still have to wear pads bc half the time the tampon leaks. At night I’m basically making make shift diapers out of pads and am up every 2-3 hrs dealing with that. I took one of those thick pads from hospital when I had her thankfully bc I would be changing sheets like crazy. Does anyone know if it will ease up or if I can get back on BC so it will lessen the amount of times I have to deal with this? I don’t see how I’m still alive with as much blood loss as I’ve been having.
