I am 41 years old and have struggled with fertility due to having polycystic ovarian syndrome

I am 41 years old and have struggled with fertility due to having polycystic ovarian syndrome. I started a diet and exercise program in October and once I started losing weight, I began having regular periods. Today my period is 8 days late so I bought a pregnancy test and it was positive. I am skeptical of the positive result given my history but will be seeing my doctor tomorrow to confirm.
