Hi ladies. Is anyone here who is pregnant with their second or more experiencing braxton hicks contractions? If so, are they quick or just dull and long? I've had a period of a half hour or so where my stomach tightens, my back hurts, and I feel achy... and this has happened a couple of times over the last two days. I remember this with my first, but just much later in the pregnancy. My doctor said if it happens 4 or more times in an hour to come in, but it's not that frequent at all. In general, I just feel tightness a lot more lately? Anyone else?
