Is It Safe To Take Gynaset Tablets For An Extended Period As Prescribed?

My last normal period was on 23 Nov after that I didn’t get my periods till January so I went to BHMS doctor. She gave me gynaset for 3 days. I started taking 3 pills daily from 4rth feb night to 8th morning aslo i missed 2 pills ỉn between but I completed 9 pills after that. I got my periods on 14th feb . It was a 3 day period after that I was having little spotting like white discharge not much. Then I was sexually active after a week after two days I again got my periods. So I went to doctor she suggested to take gynaset for 15 days 2 pills each day after that I will get my periods and I have to do blood test when period comes . So I am very scared like is it ok to have so much tablets again? Or should I consult a gynaecologist? I don’t know what to do. During my periods I only hat leg pain nothing more. I am worried
