Pregnancy facts, is it true?

Is it true that when you're pregnant usually (most of the times) you'll get really pissed and annoyed at certain especifically person the whole pregnancy? It could be anyone, your partner, a friend a relative etc. I've had many women that got pregnant in my family or just people that I know who told me they got really annoyed by just the presence of certain person during the whole pregnancy. Does that really happen? If it does, I already know who'll be my target. (Mom in law) lols.
