PCOS and missing my period

I have PCOS so I normally have irregular periods not a big deal to me. But I am 5 months as a newly wed. I am 26 days passed my period. And today I felt dizzy, feeling really tired for about a week , and very odd cramping feel inside my vagina. I’ve never felt that before. At this point I am waiting to see if I skip a second month. Not sure what to do, has anyone been in this situation before?
