First month ttc / tww Pcos.. advice? Please!

I’m in my tww.. . AF Doesn’t come for another five days no symptoms and dry CM could I still be pregnant? trying to stay positive just a little nervous... i have regular period and can usually feel when I ovulate ( cramp on one side two weeks after period ends.. cm changes ).. I work out and keep my weight down.. recently started taking prenatal pills for about a month now.. no other meds.. I haven’t tested yet I want to wait till af is late.. any one else been through this and been pregnant?
