Pregnancy loss

Last year I lost my son in august at 15 weeks pregnant. I found out in april i was expecting again but had another loss at 7 weeks on june 24th. I bled for a good 2 weeks and it started getting light but then july 16th i started cramping and bleeding heavy. I’ve been between spotting and heavy bleeding since then. I figured i got my first period after my loss but it’s lasted almost 2 weeks now and the bleeding will be heavy, spotting, almost non existent, then start heavy again. Is this normal? I don’t remember bleeding this long last year but honestly I was so devastated I could have and just forgot.
