Any advice ladies

Good morning ladies... let me start off with saying that my last 2 pregnancy ended up in miscarriage.. the recent one was on Easter Day of this yr... I have always had a hard time getting pregnant... fast forward to today... today my period is due according to glow... but for some reason I had a gut feeling about being pregnant.. so I bought a test before coming to work.. went to the restroom and what!!! A line right away pops up... my ass is pregnant... I know it’s sooo early in, that I might have another miscarriage.. but what if I don’t.. what will I do then.. I’m 37 just start a good job with county... I have a 15 yr son and a 11 yr daughter... should I tell the father??? My boyfriend lost his baby girl 5 yrs ago.. she was 1 1/2 not sure of what. He doesn’t like talking about it much... he has told me before that if I find out that we r expecting, he would want to know right away, as soon as I find out... but idk if I should... same gut feeling of being pregnant, I have a gut feeling I’m gonna have another miscarriage... I don’t plan on telling nobody in my family this time around until something happens... any advice will help...
