Probably stupid to ask but..

Alright so I'm currently 18 weeks pregnant! And my man knows how I get now. Horny and what not. Ladies, he bought me a vibrator. But I use it for just clit stimulation. So I noticed now. That when I have an orgasm. My belly becomes hard. As. A. Rock. Is this normal? I feel like it is. But I don't wanna be stupid and assume. Help me out? #Newtothismommathing
