Hello ladies. My cycle normally comes every 26 days and today makes day 29. My cycle has been coming every 26 days since January 2022. However, I do have PCOS. I do have a feeling like it's trying to come on. Do I need to wait a few more days to see if it comes on before I test or will it be ok to go ahead and test since I'm already three days late. I don't want to test and it reads a negative result.
