Low sex drive

Any advice for how to boost sex drive? Apparently when I'm pregnant it goes to non existent and my husband is the one that suffers. This happened with both my pregnancies so far. It doesn't help that I work from home so I'm in sweats most days and rarely wear makeup and I take care of our toddler when he's home from daycare. He thinks that I don't care to please him anymore. I try, I do. We have sex 2-3 times a week but because I'm not into it he says it doesn't count. I'm going to try and wear makeup more often and look "presentable" even though I never leave the house except to run errands and drop off/pick up our son from day care. Any one have experience to help boost their sex drive? I just want to enjoy it again
