Clots & Period

So, I have had an odd period this month. I started spotting Thursday 7/18. No big deal, right? Then my period actually started and was normal flow. This was different as it normally starts super heavy. The past 2 1/2 days have been filled with swapping out my pad about every 3 hours. I felt something weird about an hour ago, so I decided to check it out. I had quite a few clots that were different than the normal clots I have. These were like harder balls than a normal clot that I have. I have no idea what to do... is this normal? 😅
