Dear Pregnancy hormones

What exactly is the point of making me exhausted and then when it's FINALLY time to sleep I can't!! How does this help baby develop?

Also what does the onset of constipation do for baby's development? I am just stumped by that one... Does an hour and a half of contemplation and pain on the toilet make my baby develop perseverance?

Irritability? Mood swings? What about the swelling in my feet? Or my sudden hatred of being touched by those who I love? I would like some answers hormones!! Because this is bullshit!!
