Take PT or wait

So as of today my cycle is 9 days late. I had a cycle in January 18-21 then I had another one in February 28,29,1,2, and 3. My fertile days was February 8-14. My ovulation day was the 13th. My fiance and I baby danced 12,13,and 14. My cycle was suppose to come on March 27 but aunt flow did not show. My breast are really sore, I been feel nauseous a little and I'm having little pains in the lower part of my stomach. I was diagnosed with pcos last year but I have had 2 natural cycles this year. Should I take a test??
