Every pregnancy is different, so it's hard to say exactly what you will feel and when. There is no set number of times on how often you should feel your baby move. Your baby would have started moving right from your first trimester itself, but you might not have felt it. An early ultrasound scan at seven weeks of pregnancy, can pick up your baby's movement. However, you may start recognising your baby's movements only in your second trimester. 

When you will feel your baby move depends on certain factors: 

Your stage of pregnancy 

You will initially feel your baby's movements like a gentle fluttering (quickening). Most women start noticing this at between 18 weeks and 20 weeks. These fluttering feelings are very subtle. If you are a busy and active person, it's quite easy for you to miss them out. 

Initially, you may even mistake your baby's activity for Gas and bloating in pregnancy passing through your digestive system or a gurgling tummy. But as your pregnancy progresses, your baby's movements become stronger and they will feel a lot more like kicks. 

The frequency of babies' movements tends to increase till about 32 weeks. After this till your labour starts, the number of movements over a day, remain more or less the same. 

If you've had a baby before 

Identifying your baby move might be easier if you've already had a baby. You may feel movements as early as 16 weeks, because you'll know exactly how it feels when your baby moves. 

Your weight 

It may be harder to feel your baby's movement if you have extra weight around your middle. You might also feel your baby's movements later if you are overweight. 

Position of the placenta 

If you have an anterior placenta (the placenta is on the front wall of your uterus), you'll probably feel your baby move slightly later than if you had a posterior placenta (placenta is at the back wall of your uterus). This is because, your baby's movements get cushioned at the front of your bump by your placenta. 

You will get to know the position of your placenta during your anomaly scan, at 20 weeks.

Once you start recognising your baby's movements, you'll probably come to be more and more aware of them. Your baby will have times of rest and activity. As your pregnancy progresses, you will know when these happen.

Give attention to your baby's movements on a daily basis. That way you'll soon be aware if your baby has started to move less than usual. 

Contact your doctor immediately if:

1. You haven't felt your baby move by 24 weeks of pregnancy.

2. You notice your baby moving less, particularly after 28 weeks.

3. You have any concerns about your baby's wellbeing at any time of your pregnancy.

Your doctor will listen for your baby's heartbeat. If required, she will ask you to take an ultrasound scan or other tests. 

As your baby grows and develops, you’re likely to feel a range of sensations when she kicks, turns over and even when she hiccups!
