Possible pregnancy symptoms?

So i was diagnosed with pcos when i was 14 i am now 24. I have had very irregular periods since i was 11, but the last year they have been consistent. According to the app I ovulated on the 23rd of january and my period was due the 6th of this month and i still have not gotten it. The last 2 weeks i have been experiencing cramping, frequent urination, severe mood swings, fatigue, and sensitive breasts (that has now gone away). I was able to get pregnant naturally with my son, so i know pregnancy is not a far fetched idea for me. I was wondering if anyone has experienced these symptoms as early pregnancy symptoms or late pms ? Or what your guys' opinions are? Thanks in advance!
