Hi, I understand your concern. Ovabless tablet contains green tea extract & provides vitamins & minerals for good health. It does not have any specific role n conception. As you have irregular periods, I feel you should go for ovulation study ( as problem in ovulation often cause irregular periods ). Consult a gynecologist , get your cycles corrected . A normal ovulation is a must for conception. similarly normal sperms are equally essential. Get your husband s semen analysis done. Once both the things are normal you can try by having unprotected sex around ovulation day of your menstrual cycle( known by LH surge test at home ) Thanks.
