I know this may be a dumb question but are heat flashes a sign of soon to be labor? Cause I've been hot every since yesterday morning at my doctors appointment. My fiancé said he wasn't hot but I was literally sweating! And then when we got home we had the air conditioning on full blast but it was like I could barely feel the air. And then again this morning, the air's been running all night while I slept and it doesn't even feel cool to me. Is it normal to experience hit flashes like this late in your pregnancy??
