36+2 cramping and nausea

36 + 2 all day I’ve been having irregular cramping that’s pretty uncomfortable not can’t speak uncomfortable but uncomfortable none the less and just feeling sick to my stomach in general I haven’t had a problem with nausea this pregnancy so it’s a little odd for me to have it this far along. Earlier I had the shakes and my upper middle back was aching like crazy it’s aching still but on and off my cramping seems to be alternating sides ? I was induced with my first baby so I’m really confused at how I’m feeling but I’ve already had my labor stopped with the shot twice I don’t wanna go in again just to get prodded and sent home. Could this be the onset of labor is what I’m wondering tia ladies no rude comments pls
