Early PMS or pregnant

The guy I’ve been seeing and I have been very active this month. I’m 11 days away from my predicted period date.

I have been experiencing higher than normal appetite. I could be fine one minute and the next I’m starving. I’ve also been a little bloated with minor cramping (considering that I have crying, can’t move cramps during menstrual cycle). My libido has been abnormally high. Like I can’t have enough. And finally today I’ve been very nauseous. Last nights dinner consisted of cereal since I got out late and my regular tea and granola bar for breakfast. Nothing out of the ordinary. The nausea is very new.

I know PMS symptoms are very similar to those in early pregnancy so I don’t know if it could be a possibility. How early would it be too early to test? How many days before your start date do you usually start to PMS?
