Some advice?

Mommas, I need some advice! I am having contractions 5 min apart since yesterday. They are not painful, but def intense(feels like a work out). I figured they were Braxton hicks and went about my day. But I notice baby has dropped this morning (my ribs don't hurt anymore) and that I am cramping uncomfortably through many of these contractions...plus there's def pelvic pressure which is very new! Also, I have this weird feeling in my vagina like I constantly have to pee. I don't want to bother the doc if it's just Braxton hicks. I'm 36 weeks. I know if I call the doc, they will prob make me go to l&d , but do you think I'm over reacting?
