Labor soon? Help!

I'm a FTM and have no clue what to expect. I've been feeling absolutely horrendous today, (nauseous, super hard tight belly, crampy belly, headache, low back is killing me and just feel really off) the baby hasn't been super active either. He usually moves MUCH more than this (although he's still in the "ok kick range"). I don't really feel a definite steady change in the tightness/cramps from like them being there to being absent like contractions would be, but I haven't ever felt this awful and my stomach is like rock hard. I'm due Tuesday, 3/27 and am supposed to be induced Monday evening 3/26 if he doesn't come before then due to my weight. Should I call and go be monitored or would it most likely not show contractions or anything? I don't want to get sent home and just be told I'm gonna be this miserable haha
