Hi, i took pregina for 5 days and confirmed ovulation thru tvs with my ob last june 8, 2018. 1 mature follicle. I have pcos and i have a 9 year old daughter. She advised to take duphaston for 10 days, once a day at bedtime. It has been 12 days after taking the last one but still no period. Took upt and came back negative. No other symptoms aside from cramps, headache and backache. Also have white creamy cm but not that much. Thank you.
