Help !

My last period was oct 21 and it's now November 29 something is wrong with me , I haven't had sex I only got fingered maybe he had played with himself and cum without washing his hands and just stuck it in me . Is that possible to get pregnant by getting fingered ? I'm 11 days late of my period and I also have irregular periods some days they're on task and some days they're not . 😭 I'm very scared and I'm only 14 my stomach looks big is that also from bloating lol ? But just give me some tips .
