Advice ?

I have severe endometriosis and I never thought I would get pregnant the doctor told me I had a 4% chance . I have been with my boyfriend for 3 years and it finally happened I’m 7 weeks and 4 days . But there’s a terrible catch , I found out that he cheated on me , so I left now I have to go threw everything alone , I have no one to share little mile stones with such as first ultrasound I have nov 6 , or the first sign of a bump or anyone to talk to him/her . I just feel very alone And lost and hate the thought of him/her growing in a separate house hold, because I don’t have a dad so I know the pain that is caused by it . I guess I’m just asking for advice or prayers , something to help ease my mind ?
