Hi, me and my partner had unprotected sex. Her period cycle was on 17th but she get it (delayed)? We consulted a medical representative and started using duphaston 10 mg, it's been 2 days (22nd and 23rd dec, she consumed it twice a day. How long should we use it and when will she have her periods back? Please suggest the things to follow up. When to stop? If we stop after taking 6pills (3 days) by tomorrow when will her periods be back? Thanks.
