So most nights (I say nights because that’s the only time I notice it), when lying down on the couch I get this feeling every so often (like every hour or so) where it feels like I’ve gone really hot, my hearts beating faster and I can feel like pulses around my body. Sometimes this happens when I experience Braxton hicks but sometimes I get this without Braxton hicks and I just wondered what it could be? Is it something to worry about? The feelings lasts for like 30-60 seconds only.
