Help!! Need advice!

Jennifer • I was diagnosed with PCOS 10/26/15. Expecting our 1st in Jan. 2021!!!!
I have PCOS I had dark brown spotting 1/2 thru my cycle. I am 2 days late- with the update of no period it pushed me back 2days so I should get it today. I have none of my typical period signs-- 
I have been on metformin- but I was bad this month and have not been consistent. 
Has only one with PCOS gotten preggers in the first month? 
I'm going to test tomorrow or am I too early? HELP!!!
