I think I'm pregnant....??!?!?!?

I have PCOS and have been trying to get pregnant for 2 years. My period is So random so it's hard to know when ovulating, etc. 
Today I decide to take a preg test and to my great surprise - it said yes!!! So I of course took another 5 over the course of the day and they all said yes! I took the clear blue and it said I'm probably 2-3 weeks in. 
I'm trying not to get too excited - is it possible that all of my tests could be false positives?
