Sometimes after you find out you are pregnant, possibility of having twins may have crossed your mind. It usually takes 8-10 weeks before you find out if your nurse hears one or more heartbeats at your first ultrasound.

In the mean time you are left to wonder. So what are your chances?  This usually depends on the biological history of twins in your family.  So if you are a twin, already have one set of multiples or have twin relatives, your chances of having twins are higher. Also if you have undergone fertility treatments, you have a 10% chance of having multiples.

Possible signs that you could be carrying more than one baby include:

Uterus measurements are large for dates.

Excess weight gain.

Amplified pregnancy symptoms including severe morning sickness, extreme fatigue or a strong metallic taste in your mouth.

An AFP blood test result that is inconsistent with a singleton pregnancy.

The above signs may or may not mean you are carrying multiples. Also, you may have no unusual symptoms at all, even if you are carrying more than one baby. Though it is not the perfect solution, waiting for your first ultrasound and hearing from you OBGYN is the best way to know for sure how many babies you are expecting. So try to be patient and whatever is in your future will be revealed soon enough.
