Help for a to be daddy

KC • Happily married, to be daddy 01/09/2019

My wife and I haven’t been pregnant long, only 13 weeks. Even though that is roughly only 3 months we have had sex just 2 since conception. It’s driving me nuts. I have tried everything to turn her on but every time I get her excited she feels uncomfortable because of the baby I suppose. Does anyone have any insight or suggestions? This is our first baby and at this point I am feeling like this will be our only one if every pregnancy is like this.
