No sex drive

Hey!  I'm 10w 4d and I have had absolutely no desire to have sex or do anything sexual with my boyfriend.    I usually take one for the team to keep him happy, but I'm just never in the mood.  I'm exhausted and just don't care about it.  He's miserable about it, trying to understand but he just can't.  We do stuff at least once to 2x a week but apparently it's just not enough.  He makes me want it less when he's constantly on my case about it. I hate feeling like this!!!! Anyone else experiencing this???
