The 'This Is 40' star gave birth to her first child Noah in September and she was so sick during her pregnancy that she compared it to Kristen Stewart's ordeal in 'The Twilight Saga' when she was pregnant with a half-vampire, reported Contactmusic.
"It was so bad for me, actually, I was convinced that I was, like, maybe birthing a vampire baby like the one from 'Twilight'. You know what happens to Bella, where she's in cold sweats all the time?
"I felt like that was happening because I had no vitamins and nutrients and I was just nauseous," she said.
However, Megan, 26, recently said that becoming a mother has left her happier than she has ever been before.
"The whole thing has been overwhelming because I didn't know you could love something so much, and I know people always say that but I love him so much it hurts, and it's an interesting feeling to have because I never felt that before," she had said.
