Hi I just started using this app 2 months ago and so far it's been spot on period wise (quite literally) except for this month. As of right now today is suppose to be my 4th day or the calm down of my period and I still haven't started. I took a pregnancy test yesterday and it said negative. My boobs hurt really bad I'm peeing constantly certain things make me feel like im going to puke and im freezing all the time which normally I'm hot all the time. Just wondering people's opinion and thoughts
