Really concerned

Hi everyone I just really need some advice I’ve just moved to a new area so not yet registered at a doctors. Firstly I got my period just over a week ago after not having one for nearly two months I don’t know the reason why. Anyway I normally have a few clots threw out but I’m having loads everyday and not little ones really big ones and a lot of them I’m concerned as I’ve not had this many before and wondering if it’s normal for anyone else or some can give me some advice thank you 😊 xx
