Pms symptoms

So I know being moody is a major pms symptom and I've been raging like hell all day (AF due Tuesday) but tonight I left my house and cried the entire time I was in my car... all because my daughter wouldn't poop in the potty lol (we've been fighting her for a while to poop on the potty but she won't) I literally broke down and cried my lil eyes out on my way to go get ice cream from sonic. Never have I EVERRRRR acted like this a few days before AF. Don't get my wrong I pms from helllll but I've never cried like I did tonight over something to small. Am I being crazy or does anyone else cry also when pms'ing?! Please tell me I'm not the only one lol we've also been ttc and that's taking a toll on me also :(
