Super itchy belly - 37wks & 2 days

Lately, my belly has been SUPER itchy & I have been itching the crap out of it. It's only at the bottom of my stomach where I have stretch marks and up to my belly button. But it's causing me to dig my stomach bad. My feet have been itchy and so has my hands but we have a flew fleas in the house & I'm not sure if that is why they're itchy. But has anyone experienced a itchy belly?
