5. Mood Swings
According to doctors, pregnant women go through lots of mood swings. Well this is not completely true. Every normal girl have different versions of mood swings.
For example: They will make a movie plan a week prior, will do shopping for that too but a night before they cancel the plan for any silly-billy reason.
This example illustrate that one can never predict a women and their mood swings and can never find the reason behind such disastrous mood swings.
