36 weeks and feeling off..

I'm a FTM, this past week i've been feeling extremely uncomfortable but today I just can't seem to rest. My arms and legs feel tired at times like they want to fall asleep. I have on and off backaches and stomache aches. I have bad diarrehea and I just feel this pain on the side of hip It has become impossible to get out of bed and walk. I just want to know if that mean I am going into labor soon or if I am in labor. I am so confused and just wondering. Just took a warm shower right now but it is not really helping.
