I have this weird pain on the right side of my belly kind of in between my hip and my belly button and I can feel it when I suck in , move, stretch or press on it . I've also had a burning sensation under my ribs and felt like puking off and on for a few days ... I also have a cold so I've been blaming the nausea on that so it could be unrelated . I can just feel that something is there and I feel full and bloated down there ... (my period is due today and hasn't come yet so I'm also blaming the bloating and fullness on that) I've had almost burning like cramps in my uterus as well that don't feel like normal period cramps . My lower back has also been aching like crazy and almost throbbing in a way ... I highly doubt I am pregnant so Im ruling that out unless my period doesn't come . Is there anything else you girls can think of that could cause this sensation ?
