Hi, 
Thanks for posting in HCM. 
I understand your concern. 
Ovares plus tablet contains 
Dehydroepiandrosterone (DHEA) and Folic Acid. 
According to some studies available DHEA improves ovarian function and increases pregnancy chances in general. 
But usually it is not recommended in PCOD, as one of the feature of PCOD is androgen excess, which may become worse with intake of DHEA. 
Rejumet contains Metformin, which is a insulin sensitizer and helps in decreasing 
insulin resistance and improved ovulation function in PCOD. 
Folic acid is a component of the B group of vitamins and is necessary for the normal production and maturation of red blood cells. 
Ovacare is a specially designed 
micronutrient formulation to support the requirement of women, who are trying to conceive. It contains the following:
1. Inositol, which helps support ovarian function and restores menstrual cycle.
2. L-Arginine, which improves ovarian function and 
pregnancy rate.
3. Folic Acid, which plays important role in process of conception.
4. Antioxidants like Selenium helps to reduce 
oxidative stress.
Taking Ovacare could be beneficial for you. 
However, kindly consult your doctor or any other specialist (Gynecologist or Infertility specialist) before changing any medication. 
Hope the information provided would be helpful. 
All the best.
