I completely understand your concern for not having a period despite taking the tablets, but I would suggest that you stop worrying about it as this problem can be easily overcome with proper treatment. Ovral G and crimson both contain a combination of of two important hormone preparations used to treat irregular cycles. However, one of the drug in Krimson helps to decrease masculinizing effects which is an advantage that is not available with ovral G. Hence krimson is better to decrease the effects of testosterone than ovral G. As a treating OBGY specialist, if patients like you walk into my clinics, a few more details like your age and the duration since these symptoms started are other histories that help me formulate a line of treatment. From your complaint of irregular period and masculine look, one of the commonest possible reasons appears to be PCOD which is caused due to imbalance between various hormone levels. A primolute N for short duration sometimes fails to cause a bleeding as the hormonal imbalance stops the lowermost layer of the uterine lining from growing which is needed for primolute to act. The best option for you would be to first understand the cause of these complaints for which you would need an ultrasonography of the the pelvic organs and a blood test to check your hormonal status. If the problem is due to polycystic ovaries, then a Kimson for 21 days will be a better option for you. Other available treatments to reduce testosterone effctes include tablets containing spironolactone commonly sold as aldactone or finasteride that decrease the androgenic efffects. I hope this answer helps you and would be glad to answer any further queries that you may have in this regards. Thanks and enjoy good health.
