Did my IUD fall out?

Some Girl

I’ve had my mirena iud for almost a month and I started my first period with it. It’s been pretty heavy and A LOT of blood clots. Before I felt a lot of pain like serve cramps because of the iud but now I do not have any pain. Idk if i should be worried that it fell out and was in one of the blood clots or what. Any advice or anyone whose experienced the same things would be very helpful please comment. (My checkup appointment isn’t until July.)
