Not feeling appreciated ☹️

My husband has never been the romantic type and I've gotten used to it. I have accepted it and it's something that I dont always take to mind because he's a great husband and loves me. Since I've been pregnant idk I don't feel appreciated. I don't know how to explain it. He hasn't wanted to even touch me. At the beginning I got the reason why. It's because he didn't want to start anything and he thought he would hurt the baby. Now I don't know, we are in the safe zone now, I'm 15 weeks. I'm just sad I don't know how to talk to him about it.
