Have you found yourself forgetting things more now that there's a bun in the oven? Perhaps you're a bit more emotional than you used to be? Blame it on the pregnancy brain. While some say this is a made-up ailment, there is actually a scientific reason why women behave differently during those nine months. Psychologists found that women tend to use the right side of their brain more when pregnant, as the emotional and intuitive functions help them bond with their future child. As a result, they are more in touch with their feelings and tend to be a bit more sensitive. But don't worry, ladies! Once the baby is born, your brain will most likely return to its normal state, though it will suffer from slight sleep deprivation.
