I know what you are going through. My oldest DD just turned 30. Last year she had to have a hysterectomy because of fibroid tumors. She doesnt have any children and now cant. She would make a great mom, but unless in the future they can adopt that wont happen. She has really bad days with it, knowing that all of her friends are either pregnant or have children, some that shouldnt. If any medical reason is ruled out then it may be stress from trying. Try to relax. I know several people that have had a hard time getting pregnant then when they all but gave up they got pregnant. It was the stress that was preventing it. As for your husband some times men say things without thinking or the wrong way. Men are suppose to be tough and not let things like that bother them but it does and they dont know how to communicate their feelings about it. Calmly talk to him about your feelings and the things he wrote that bothered you. As for your SIL she has a long road ahead of her and from what you say wont be easy. I never have figured out why people that have no business having children can pop them out like popcorn but people who really want and will totally love and care for them have a hard time. May God give you peace and I'm praying for you.
