Being overweight may play a part in one's fertility. You should have a body mass index (BMI) between 19 and 24.9-- 25 to 29.9 is considered overweight, and anything above 30 is obese.
The more overweight your are the lower the chance of you acheiving a pregnancy.

Being overweight can cause increased risk of infertility, irregular menstrual cycles, increase in miscarriage, and lower success with fertility treatments.

Once you do become pregnant, being overweight can lead to some complications, including gestational diabetes, high blood pressure and elevated risk of birth defects.  Losing 5-10% of your weight may help improve ovulation and increase pregnancy rates and will improve overall health.
