I've Been Married For 7 Months And Now We Are

I've been married for 7 months and now we are planning a child. We had sex 'without any protection' since day 1 of our marriage. I have a regular period of 3-4 days. But still i m not able to concieve. My husband is concerned about it. 1 week ago i consulted a gynecologist. She recomended Productive f tablet for a month. Is that medicine safe for concieving?? What are the side effects of it?? Plz help.
Thank you.
