possibly pregnant?

Sophia
Okay so quick rundown, I have PCOS and I've been on metformin for 4 months. I noticed last month I had a lot of sticky discharge shortly after my period so I figured it was me ovulating a week later i started spotting. I've been spotting for a month now and here recently I've been really nauseous, tired and nipples have been darker and the duct is more open looking. I know most of you is going to say to test but I just want hear if any of you had the same thing happen and ended up pregnant?
