ok I know someone who didn't even know was pregnant for good 3 months.. Although she was cranky and getting sick all the time but she thought it was for some other reasons, now that she knows she is having a baby, her mood changed.. she feels happy, she feels like she got more energy etc and life seems beautiful to her. So for some people, yes it can be painful to go through this, but for some it's a very different experience. You'll never know till you go through this your self.
awww so sweet! :)
