Does Ovacare Help To Treat Infertility?

Hi Doc,
Am 30years old, married for 18months now.
Bin trying to conceive but have failed and of lately I have been experiencing missed periods which has resulted in my body weight around my waist. I was 55kg now 60kg.
I went through series of test (Hemoglobin, Sugar, Hormonal, Thyroid & Pelvic Scan) & By Allah's Grace all is well nothing to worry. During the time of my test, I got my periods after 5months of delay & am yet to expect them by end of this week.
My doc has put me on Ovacare n has told me to shed my weight, cut down on sugar & salts.
I would like to know does OVACARE really help to conceive and streamline my monthly cycle? If yes then what are my chances on conceiving and becoming fertile? I want to reduce my weight around my belly advice me how.
Thank you
