Regulating period and blood flow

Any ways to kind of regulate your period and the amount of blood flow you have every month? I read a few things online, but was just hoping to get some advice from women who have tried this. I've always had somewhat irregular periods, id say between 30-40 days. Not terrible but still annoying...and since my ectopic pregnancy in February I've have 2 periods that seemed VERY light and just weird (I've have a period every month just a few that were lighter) So I'm just hoping to even things out and get everything going back to normal. Anything would be appreciated!
