Embarking on a pregnancy only in late thirties is becoming common for various reasons such as, finding a partner late, awaiting career stabilisation, etc.

BENGALURU: Embarking on a pregnancy only in late thirties is becoming common for various reasons such as, finding a partner late, awaiting career stabilization, etc. Many concerns may arise in one’s mind when considering delaying pregnancy. ‘Am I likely to have some difficulty in falling pregnant? Am I more likely to have a miscarriage? Will the baby be okay?’ The list goes on.

With various sources around painting a not-so-positive picture, it is but natural to feel gloomy. However, it is not true that all odds are stacked against you. Most women in their late thirties with regular cycles have about 25 percent chances of conceiving per cycle. The most important factor seems to be hitting the bull’s eye at the time of ovulation, which is a window of about six days (five days prior to ovulation and a day after ovulation). However, getting stressed about finding when one has ovulated is not going to help. Enjoying regular sex and increasing the frequency during the fertile days would certainly help increase the chances of conception. About 70-80 percent of women fall pregnant in their first year of trying without protection.

Should I consult a doctor before pregnancy?
Pre-conceptional counseling is extremely important for someone considering pregnancy especially so, if in late thirties. It involves the following:
■ Folic acid tablets to prevent neural tube defects (defects in the brain and spine) in the baby. Ideally, the tablets have to be taken at least one month prior to conceiving.
■ Screening for any pre-existing conditions such as hypothyroidism etc and optimize control
■ Vaccinations for certain infections such as Rubella ( German measles) etc
■ Advice regarding balanced and regular meals
■ Focus on fitness and improving core muscle strength
■ Advice about avoiding smoking (both active and passive), alcohol and drugs

Will the pregnancy be at a higher risk?
Pregnancy complications seem to be related to pre-existing conditions rather than increased age alone. There are some important aspects to consider in a pregnant woman over 35 years of age. Some evidence says that there may be a higher risk of miscarriages (general population about 1 in 4). However, this may be related to other factors such as obesity and stress.

In advanced age, certain tests will be performed during the third month in order to determine the risk of the baby having a chromosomal abnormality like Down’s syndrome. Also, screening for risks like the development of hypertension in pregnancy and small babies are advised.

There is some evidence to say that women over the age of 35 are more likely to have a cesarean section but the evidence may be skewed due to other contributing issues such as obesity.

In general, the woman is encouraged to be as physically active as possible. There is no reason to avoid work or the commute if all is normal. Informing one’s boss/manager/colleagues can be done once the pregnancy is confirmed and the scan shows a normally developing fetus. The stress of any kind is to be avoided.
