Decreased libido, supplements or no?

So I have been married for almost five years now and my husband and I now have a 15month old. Well I started to feel a decrease right after I got pregnant and it has not come back yet. Now don’t get me wrong I am still very much attracted to my husband but when it’s time to be doing the do, I just never really want it like I used to and I feel like when we do I don’t enjoy like I used to. So my question is what do you all feel about libido supplements and what are some good recommendations? Thanks in advance
