No drive

So a little background. I’m 7 months postpartum. I had a super low drive after I had my daughter (never have had a crazy high one to begin with) but when we started going to the gym it went up and we were having sex regularly. Now, we’re still going to the gym, I love my husband and am attracted to him, I want to have sex and feel close to him but I just can’t seem to get in the mood. It’s been over a week now. He’s so awesome and understanding about it all but I want this part of our marriage to be great, just like the rest of it! Any advice?
