Weird period

My periods are usually long, heavy and painful, however last month it only lasted around 3 days and it was really light and jelly like. Now this month, im on day 7 and there’s no blood just dark clots that are mainly big. I’m only getting cramps around the time the clot happens but not like i do normally and the only period symptom i’ve had is fatigue and sore boobs. I did get my implant replaced 6 months ago but had normal periods since then.

Has anyone else experienced this?
