Clots with Nexplanon?

i got the Nexplanon implant at the start of the month (7th) and at first my period was late so i assumed that was me and it would stop but on the 24th it came and i’ve had it since. it’s been 9 days and generally my period is very light and lasts around 3/4 days and initially my period was light but suddenly a few days ago it got really heavy and today i noticed a blood clot. i know the implant can cause changes to my periods but should i be worried about the clot? just as i’ve never experienced heavy periods or clots ever before.
