Long labor...HELP FTM

3:30am this morning (February 26th) I woke up to mild contractions. It's 10:41 pm and they havnt stopped. They are definitly increasing in pain but they have been between 5-10 minutes all day long. The past 2 hours they have been so painful that I started getting nauseas and eventually threw up. Guys I am so tired both physically and mentally. It's been 18 hours of this shit. My doctor said that it isn't considered active labor until they are 3-5 minutes apart. Have any of you experienced mama's been through this before? I'm dilated to a 2 and 80% effaced. 37.5 weeks. I'd love to hear your experiences or your advice
