Hi, I am monika. Married from last 2+ years. I am trying for a baby. My cycle is long. It will last 40 days sometimes. I have done follicular scan starting from 12th day small holes, 15th day 10mm and third is on 17th day 10mm again in left ovary. Doctor suggested for crina n for 10 days. Kindly suggest? I am not able to identify my ovulation day as well how crina will help in conceiving.
