If you are currently taking an oral contraceptive, there are varied views on whether you should allow your body some time to "recover" from its effects before actively trying to get pregnant.
Some experts recommend that you stop taking the pill two or three months before trying to conceive because, as well as preventing you from ovulating, oral contraceptives cause changes in the lining of your uterus. These experts believe that if you did accidentally become pregnant, the embryo might not be able to embed itself in the uterine wall. The changes in the uterine lining take a few menstrual cycles to correct, so if you became pregnant immediately after stopping the pill, you might have a higher risk of miscarriage.
Some doctors recommend allowing a month or two simply for your body to adjust itself to its natural cycle; others point out that the hormones from the pill are eliminated from your system as soon as you have your next menstrual period, so if you are keen to conceive, you should go ahead.
In the past, when doses of hormones in the Pill were higher, there used to be worries that getting pregnant while taking the pill, or just after stopping, would be harmful to the developing embryo. But more recent research has found no evidence of an increased risk of abnormalities. Your baby won?t come to any harm if you get pregnant straightaway.
The Family Planning Association states that usual advice is to "wait until you have one normal period before trying to get pregnant", as this will help your GP or midwife to accurately predict your due date.
Taking some time before you start trying can help you ensure that you are in the best of health for pregnancy, such as taking folic acid as soon as you start trying, stop smoking or make other lifestyle changes.
Once you have stopped taking the pill and are trying to get pregnant, it is a good idea to note the dates of your menstrual periods. Knowing the right date of your last period can assist doctors in checking the progress of your pregnancy, as they will have an accurate idea of when your baby was conceived. An early ultrasound dating scan also help date your pregnancy.
