SO itchy!!!

So, lately my belly and my boobs are SO itchy!! This is new within the past week or so and it's really driving me nuts. I'm sure it's just because my skin is pretty much streched to the max right now, but I just can't deal with this constant itchiness - I'm miserable. I've tried everything that I can think of. I have a few different pregnancy products that are all supposed to help prevent strechmarks and itchiness, but nothing seems to help the itchiness. :( The good news is that I don't have strech marks yet (knock on wood!!)
