got pregnant for the first time and i’m absolutely terrified - need advice

I realised my period was 2 days late and i was panicking really badly so i took like 3 pregnancy tests and they all came back positive. i’m 22 and me and my fiancee still live with my dad and we don’t have much money so i am definitely going to get an abortion. i’m just terrified this is my first ever relationship and it’s the first time this has happened to me and i recently began a new job making me more stressed. i’m gonna try go the pill route but if anyone has any advice or stories i’d really appreciate it cuz i feel so alone
