I pray to god that I can make it through this week (it is my last week of my 6 week externship and if I were to drop out now I would have to re-start all of my hours over), but I have been having some pretty intense contractions last night that made me want to throw up. I've had two more this morning but they have all been very irregular so I don't think they are true contractions. I'm getting so scared, I'm definitely calling my doctor if I have any more.
