Take the time in this first two weeks of your cycle, before you ovulate, to look at what you eat on a daily basis-if you and your partner (see Dads: your diet counts too) make some simple changes to your diet, it might just improve your chances of conception.
Use this opportunity to check your weight ie. your Body Mass Index (BMI) since a BMI of under 19 or over 24 could adversely affect fertility.
If you're overweight, excess fat tissue may affect your metabolism and hormones and you may not ovulate as regularly, or at all. If you need fertility treatment, the chances of success are also lower if you're overweight, because you may respond less well to the drugs that stimulate ovulation. Once you're pregnant, being overweight can also cause an increased risk of complications, decreasing the chance of carrying the pregnancy to full term.
Weighing too little when you're trying to conceive isn't healthy either. Pregnancy takes its toll on a woman's reserves, so a little stored fat is a good thing for mother and baby. Being seriously underweight can affect ovulation and make periods irregular or absent, and conception unlikely.
Your BMI when you conceive is also a good indication of how much weight you should gain once you're pregnant, so it's worth getting it checked at this point.
