Blood test needed or PCOS causing missed period?

Hi all!

A little backstory before I ask my question.

I’ve had PCOS for around 12 years. I’m 26 and my husband and I have been TTC for 7 months.

My periods and ovulation days have been normal since January. I haven’t missed a month until now. I’m 20 days late with all negative tests.

I’m torn on going to the doctor and getting a blood test or just waiting to see if I’m just super late because of pcos. Anyone else have anything similar happen to them? What would you recommend I do?
