Possible labor???

Whitney

So I am 33w and 3days. I have been having Braxton hicks since the end of my 1st trimester. Here since Saturday it's been getting a lot worse. It feels like my vagina is super swollen and is in pain. I woke up from a nap today and just haven't felt right. Well like an hour or so ago I threw up, having diarrhea and can't breathe much!!! I have a doctors appointment tomorrow but I hate saying anything because my anxiety plays with me and I feel like he's going to tell me it's nothing!!! He hasn't even checked me to see if I'm dilated. I feel like I'm going crazy!!!
