TMI clotting during cycles

Hi ladies so I started my cycle and yesterday I felt this big blog come out I noticed lately since I had my daughter I have been clotting larger than normal I don’t recall having clots so big only when I miscarried and I had multiple my last cycle I had large clots the size of a plum and it kind of worried me I called an Obgyn but missed the call back it’s hard to get a hold of someone but anyways I spotted 3 days before expected period and didn’t get a flow until 3 days later and it was for 8 days I tested 3 times and all negative and I just got my cycle again and another clot not as large as the last but larger than a quarter this was the size of a dollar coin idk if that is normal I want to see a dr but what if it’s nothing serious when I was pregnant with my daughter they said I had a clotting disorder but nothing to worry about so I wonder if its that
