Shed some light?...

I had a heavy flow this month for 3 days. (which is long for me. I usually don't get periods and when I do it's one day of spotting) Then for 4 days straight it completely stopped- not even a hint of color or blood when I wiped! Now. I'm bleeding light red and having weird jelly like clots. What is going on?!?! Someone shed some light if this is normal// should I call my doctor??
