No sex drive? TMI maybe?

Elizabeth
For some reason even before Pregnancy I just have No sex drive at all! Okay... Maybe when I've had a little too much Wine😂 
But I'm not sure why? It's just not something I really care About, I'll do it but not really for me but for him... 
Anyone else? What can I do? Anything I can take while pregnant? 
I just feel like every relationship needs sex & if I don't start giving it more it's just going to cause more problems then it already has.
