2nd cycle after loss very heavy with severe cramping, normal? or not?

I had a loss in my first trimester, and my 2nd cycle started today. Normally my cycle is very light lasting 4 days tops with no symptoms except a migraines.. kve had a migraine since Sunday and having very heavy cycle with severe cramping and tender breasts. I thought I might be pregnant but no.. my first cycle was longer than normal but light and no cramping or symptoms. is it normal for your second cycle to be like this after a miscarriage? my miscarriage was Feb 20th, my first cycle was April 1st if that's useful. thank you very much for any advice.
