Hello, I'm Suffering With Pcos Since Many Years. But There

Hello, I'm suffering with pcos since many years. But there is no full stop to that problem. I'm still not yet pregnant. Recently, my doctor suggested regestrone5mg thrice a day and my prolactin level is nearly 80. I completed the dosage of regestrone 4 days back. So my period is not started.How many to get period after the usage of regestrone. Is there any chance for pregnant?
