I’m pregnant right after a chemical and no period in between

So September 29 I had a period. My cycle are usually 27 days long so I my next period was due October 25 on October 21 I found out I was pregnant. (The test below)

I started to miscarry Friday morning. I had spotting while I was at work but wasn’t to worried because there was barely any an it was light pink. By 5 that night I was at my second job an I start cramping more which I wasn’t worried about at first because I had been cramping for almost 2 weeks. An hour later I’m bleeding more and so I go to the emergency room where they confirm I am losing it. So I just counted it as my period it last as long as mine an since I was so early. Fast forward to now today I’m 3 days late an this is my test.

I’m happy I really am. And so grateful to god. I just hoped maybe there was someone out there that needed hope or maybe can relate.
