Pregnant after being told it would never happen.

I'm 7 weeks pregnant. I was told it would never happen. I had surgery at 18 for severe endometriosis. I have felt the fear from thinking it would never happen. It did and now I'm trying to trust God, I believe everything will be fine but you never really know. I just have been frustrated lately, My husbands sisters are having a rough time in their lives. One is in the middle of divorce and the other one isn't happy we are pregnant because after having her second child in her teens and giving the baby up for adoption she is angry we got pregnant before her/her husband. We got pregnant on our honeymoon, We didn't get pregnant to hurt anyone, and with my medical history and reproductive issues. I know how truly lucky and blessed I am. And because of their feelings even there mom sometimes acts standoffish towards me, because my husband and I expecting hurts them. I have been so supportive and helpful to them, I know how much women struggle and how much I'm blessed so when I'm being treated bad and made to feel like my baby is something to be ashamed of It makes each day very hard. Just posting my thoughts. Hoping to find some supportive moms out there.
