early signs of labor??

I woke up this morning feeling super nauseous all of a sudden and having stomach issues (diarrhea is super fun) I've just been taking it easy and staying hydrated but I noticed that when I do get up from my binge watching Scandal (lol the things we do to pass the time) the lower abdominal pressure is almost crampy. I've been texting my cousin and she said that's what she experienced before going into labor! I'm only 35 weeks, my wife is away on business and my parents are on vacation. Puhleasssee tell me these are FTM jitters and I'm not actually going into early labor. If so, how long before I should go to a Dr or L&D? My weekly check up and NST are Friday
