First period after implant removed

Hi guys. Sorry for the TMI but I’m just a little worried.. I’ve never really had a lot blood clumps when on my period before my implant (I only had one implant my entire two years on the implant) and all day today I’ve had serve cramps, heavy bleeding and a LOT of these black blood clumps. Is this normal? I’m just a little concerned is all... thanks guys in advance - means a lot x
