Help!!

Ok ladies, i keep getting headaches and very crazy hot flushes where I have a few mins ov total over heating feeling like I'm ready to collapse and during those few mins I get incredibly sweaty, I've recently been getting bad cramps at the lower stomach and when I pee it doesn't burn but after I pee my bladder still feels full and very saw for a few seconds, anyone had experiences like this (I'm also 10 days late)
