Thank you for your query regarding wanting to conceive.
In your age group, in a women with normal cycles and no known risk factor 15-20 percent of women conceive per month. This increases to 85 percent couples at the end of 1 year and 92 percent couples at the end of 2 years.
Do start folic acid tablets, maintain your weight within normal limits, exercise and try for regular intercourse every 2-3 days. If you still don't conceive beyond 6 months then a formal visit to a Gynaecologist and testing is required.
