So even tho I’m not a first time mom, I am a mom who has a high pain tolerance when it comes to labor. So I been getting what feels like hot flashes on my lower back. Could that be a sign of contractions? I never felt this before, but it’s very uncomfortable. Plus I been dealing with a lot of nausea for the past two days. I can’t sleep or really be comfortable. My husband works 3rd shift and I’m just worried about going into labor while he isn’t around. Could I be going into labor?
