I was supposed to start my period yesterday and usually it happens the night that glow says but while I'm sleeping. This is going on day two that I was supposed to have my period and there is still no sign of it. Usually I get leg cramps and stuff right before my period starts but I still haven't felt anything like that. I've never been late other then one time right after getting off the pill which was several months ago. I tested with a 88 cent test and it showed negative. Should I wait until tomorrow and retest with a different type of test or just wait and see when it will happen?
