Sending nudes?

So I have never in my life sent a boyfriend a picture of my boobs or anything else. Well I'm currently 19 weeks pregnant and decided to send my boyfriend a risky picture while he was at work (it look while for me to get the courage to actually do it) He literally never responded to the text and didn't even mention it when he came home. I feel very awkward and embarrassed. Idk what to do!
