Baby coming soon?

I feel silly asking this especially since this is my third baby but has anybody had a day where baby dropped and then they were sick throwing up the whole next day? I can’t keep anything down my vag hurts so bad and I’ve been having on again off again contractions. If you did have a day like this did you give birth shortly after? I’m 37 weeks exactly today and he’s measuring big so the doctor thinks he will be here between 38-39 weeks. This is a totally different experience for me since I was induced with both my other boys and I just want to know if it’s just pregnancy or if I’m in the final stretch of days...
