Not being able to give him a baby 😔

My heart hurts. After three miscarriages and no positives lately I’m worried I cannot give my DH a baby. He doesn’t think anything is wrong and give it a few more months before we talk to the doctor about it. He is so excited. He talks all the time about a little baby and yesterday asked me about baby names for both a girl and a boy. My heart is literally broken. Even if we do get pregnant I don’t want to tell him until I’m after 12 weeks. I don’t want to get his hopes up again. Every time it’s been positive it’s all he can talk about and then his heart is crushed and all he does is sit there and try to support me but I see how it’s hurting him. 😔 just a rant.
