Day 129 of 280, second trimester
You are 18 weeks and 3 days
Wanting to protect your baby is a natural maternal instinct, and it has probably started already.
151 days until your due date
It's natural to want your baby to have the best start in life, but this can lead to unnecessary worry about his health and wellbeing.
You may find yourself worrying about things that never bothered you before. For example, you may use a computer regularly and suddenly worry about radiation from it.
Try to relax and keep worries in perspective; your baby is very resilient and well protected in your uterus. If you're concerned about lifestyle issues or your baby's development, your doctor can give you information and reassurance.
Meanwhile, look after yourself by eating well, exercising regularly, and going to all your prenatal appointments.
As a matter of fact
Computers are safe
Computers don't give off enough radiation to affect an unborn baby.
Many studies have looked at the low-level radiation from computers and laptops and found them to be safe.

Your main concern
Caring for your baby will become your main concern, and there's unlikely to be a day when you don't think about your baby's wellbeing.
Ask a Doctor
What are the risks of gaining too much weight?
Women who overeat in pregnancy tend to have bigger babies, which can make delivery harder (the baby is more likely to get stuck) and increase the chance of a cesarean.
Overweight pregnant women are also more likely to have complications such as gestational diabetes and preeclampsia, and their children may be at greater risk of diabetes and obesity later in life. Most research focuses on women who gain more than 40 lb (18 kg).
