He broke up with me, and now I’m late

I was told that I had PCOS when I was 16, never took great care of it so I went on with my life. Fast forward, went on metformin, lost 30 pounds, meet my ex, doctor told me that I’m fertile w/o any test since I’ve been ovulating, he broke up with him a month before our anniversary, and now I’m 2 months late! Went to the doctor negative result... going back in 2 weeks. Idk what’s wrong with my cycle.
