Hi, welcome to Spider ID. 🙂 This is a Crab Spider (Thomisidae), maybe Xysticus funestus if the top of the spider is as unmarked as the bottom (your image is showing the underside of the spider). https://bugguide.net/node/view/508422/bgimage

They’re not considered to be of medical significance … everyone’s immune system is different though, so of course see a doctor if you have any reason for concern regarding the bite. They’re not typically aggressive but can certainly bite in self defense if trapped against skin.
