Clear watery discharge instead of period

Ok, to start, according to eve, i am 39 days late with my period. I have been getting what seems like gushes of clear watery and odorless discharge when I bend over to do things or stand up. Haven't really been nauseous or anything been have noticed my stomach being itchy around the belly button area and a few new stretch marks on each side... The itching I just assume is the starch in my new uniforms (recently changed jobs from Publix to Disney). And the stretch marks I just... Well I'm a bit heavy anyways, so...

After all that said, could I be pregnant or just something else?

Thanks
