So I'm currently 9w2d pregnant with my second child first is 6 years old I find out since I was 4 weeks, anyways so my bestfren been trying to get pregnant for about 2 years with no luck went to so many doctors they can't find any issue with her I wasn't even trying n got caught, I don't know how to tell her I'm pregnant because last year her cousin got pregnant n her behaviour wasn't nice towards to the girl even try to tell the girl husband the child might not be his, when any1 she knows got pregnant the way she does bad talk them I'm so scared .. She was that jealous of her own cousin.. Now everytime I'm around her that's when my morning sickness does be the worst I keep saying girl it's the flu.. a few days ago me and her was talking she started to cry telling me how her bf does say she can't make kids n he gonna have to leave her they was to get married he called it off saying he'll not marry her till she prove she can make a child he don't wanna tie his self to her n won't have kids in the future.. pls tell me how to break the news to her I know she's gonna have a lot of stuffs to say n might even be mad but I still wanna tell her
