Is it safe to take Krimson 35 to regulate periods?

Hi doctor,

I am 25 years old and my menstruation cycles had been irregular since the start. After 1.5 years of irregularity (missing periods for many months), I visited the gynecologist and after seeing all my tests results, my doctor told me because of my obesity I had irregularity in my periods. He prescribed me Diane 35 for the first 21 days post that I got my menses and thereafter he asked me to continue with the normal course of Krimson 35 of one tablet a day for 21 days. Thereafter my menses became regular while being on the medicine. After one year, I discontinued the medicine out of fear of side effects and thereafter my menses continued irregularly again.

During my late teens and early 20's my menses were highly irregular (missing for more than 4 to 6 months) but from last two years, it occurs monthly either with heavy bleeding for 1 to 2 days or very light bleeding or spotting for 10 to 15 days. I am not on any medication right now nor do I have any other symptoms like cramps or nausea or any other menstrual symptoms. However, I still continue to be obese and did develop some levels of facial hair around my chin area. Could you please let me know, if I could go back to starting Krimson 35 to get everything back on track? Will there be any kind of side effects? Will there be any difficulty in conceiving at a later stage of my life?
