Low libido.. HELP! :(

After having our first child my sex drive has gone down.. We went from sex every single day for the most part to hopefully once a week.. And I hate even doing it then.. Are there any kind of natural supplements that I could take to help! Really want baby number two but my body doesn't want to try anymore! :( I've seen where people are taking mucinex or preseed to help??!!! I'm desperate to just feel better about myself and to satisfy my man without feeling like get it over with! Uh
