This ended up being one of those dirty little secrets of labor that no one ever tells you! At least in my case.
I vomited with every single contraction for 12 hours. After there was nothing left, it was all dry heaving and that nasty bile stuff. ugh! I had no idea this happens to people. They were pumping zofran and phenergan into me, but they didn't help. I wasn't nauseated, just couldn't stop vomiting.
My poor husband was following me around with a barf bag. At the time it didn't seem like a big deal. The contractions were so strong that vomiting was the least of my problems. But it would have been nice to rest in between those contractions of transition instead of puking.
Did this happen to anyone else??? I got an epidural for my last hour of labor and ONLY THEN did I stop puking lol. I'm really hoping I'm not sick this time!
ETA: despite all this I STILL have really fond memories of my labor and delivery Truly the best day of my life.
