Is this the start of labor?

It’s 2am and I woke up feeling like I needed to poop. I went to the bathroom and nothing, a little gas that was it. I came back to bed but couldn’t sleep bc I feel like I need to go, then I also started to feel like I might throw up, however 30 minutes later nothing and I still feel this way. I tried to go several times but nothing just a little gas. I’m having some aches in my back but nothing crazy. I’m wondering if this means labor might he starting? I’m full term
