When i was pregnant with my baby boy i had bad morning "all day" sickness. I lost 20 pounds.i had really bad headaches could barely eat and i swore i never wanted to go thru that again especially after 27 hours of labor. But that all quickly faded away. Now hes almost 2 and i would be more than happy to be nauseous and sick and have a headache if that means growing another little one. Lol its all so worth it.
