When women are at least two months pregnant, they tend to be so scary. In fact, you as a man must be psychologically prepared for this. She may frustrate you or disappoint you but the next moment she will make you happy again.
Their moods keep on fluctuating in the following ways: One minute she's crying and the next she's laughing hysterically; This appears quite ridiculous but you should learn how to deal with it. She may be happy and laughing for around five minutes but thereafter she shifts immediately to sadness and crying. Just relax and be near her when all these happen.
When in the bedroom, she's all over you for one minute and the next she doesn't want you to touch her completely. In fact, she doesn't even want to look at you directly. How long will these mood swings last? Please don't worry brother because you know how long the pregnancy lasts. In a situation like this, be always available when she needs you but again run away when she doesn't want you to be near her.

There will also be constant complex biochemical changes: sharp dips in blood sugar, hormonal fluctuations, and water retention. All of these things can cause her mood to shift in a nanosecond.
