having a libido problem

So I got married two weeks ago. (Yay!) anyways, when my husband and I started dating, we were having sex about every day or every other day for two weeks straight . After those two weeks, my libido dropped and it's just been really hard for me to get hot and bothered. I don't want to say it's taking a toll on our relationship but at this point sex for us is just a chore and I don't want that. I want the passion and fire like I had those two weeks. Any suggestions? My husband and I had talked about it, tried to even "get me into the mood" sometimes it works over times not so much, I just feel like I'm letting him down because I don't do it like we used to.
