I am under the process of TTC for past 8 months. Last cycle i took Clomoid for 5 days, i undergone for follicular study, but till 15th,18th day , only small follicles are found. My doctor asked to take Gestin 5mg for 10 days from the 22nd day of my periods. Now I have crossed 12 days after the last pill of Gestin. Still I didnt get my periods. What may be problem ..
