Please help me understand these blood clots?!

TMI WARNING ⚠️

So today, and maybe the past couple days, I noticed I’ve been having large blood clots. It’s very atypical for me, and I’m not sure how to go about it. My mind obviously resorts to miscarriage right away because it’s easy to freak out about things when you don’t know what’s happening.

The clots weren’t goopy and squishy like some past blood clots have been. I tried to feel it (gross ik) and it was like hard to rip apart.

I have an IUD but i’ve been having IUD complications lately, the first one I had for about a month was in the process of expelling and I wasn’t aware until I had to get my follow up and my gyne had to pull it out. My period lasted for 40 days with that IUD (abnormal).

I got my second one inserted 3 days after that and have been having a lot of cramps for this one. My period is starting up again but with very heavy clots, i don’t know if this is typical. I’m just not really used to the IUD process because my first one expelled in a month and I’m new to my second one. I honestly don’t know if my IUD has anything to do with it. but if anyone can provide some guidance, it would be much appreciated
