Just as I was getting out of the car after work today, I kind of felt a tightness in my uterus and when I touched the bottom of the bump it felt sort of tight. There was no pain or discomfort and it hasn't happened since, I have not had any watery discahrge or something but I am soooooo paranoid about premature labour! Does this sound like it could have been a Braxton Hicks? I don't really know what they are but I have heard they can happen in second tri. Like I said there was no aching or anything but it just really worried me that there was this tightness. It probably only lasted about a minute. Can anyone advise? If it happens again should I call the m/w or does this sound normal? UPDATE: Think this might have just happened again! That is two and a half hours between them, does that sound like it could be BH? Again, no pain or discomfort, just a tightening of the lower uterus (really not that far above my knicker line) and it felt hard to the touch. Lasted about 30 seconds. Should I worry?
