Please help...

So the first picture this was supposed to be a period but this started on the 25th of July instead of a period and lasted 2-3 days, about a 1-2 weeks after I threw up watching step up which I was annoyed because I almost got our lovely living room rug but missed thank god and now this 2nd picture happened about 2-3 days ago,I was complaining that my period hurt which I never ever have period pains ,I was in the kitchen when I literally felt something drop and so I told my partner I was going to the toilet but obviously to have a proper look because I’d never had this happen before and when I looked I saw what’s in the second picture immediately shouted my partner from downstairs who came and had a look because it scared me, he said the first thing that he thought it might be which was a miscarriage, is he right?

Please help guys I also worked out from the 25th July till the 2-3 days ago that it’s 28 days and 28 days is 4 weeks,... I really need some help or advice or something please ...
