Hello, I Am 26 Years Old And Have Pcod From

Hello, I am 26 years old and have pcod from last 1 year. My gynae prescribed me oosure forte, glyciphage and F029. I took smartova on the 4th day of my period last month. I was supposed to get my period on 15th September, but it has still not come. it will be almost 2 weeks now. I took a hpt on 15th Sept itself but it was negative. Should I be worried?
