The last week or so I've started having a lot of braxton hicks, some painful, as well as a lot of achiness around the whole bump and my lower back. Today I get braxton hicks as soon as I get up and move about, walk up the stairs or get stressed in anyway. I've also had a couple of quite painful ones, 5 all in all during the day. Should I worry about it, or is it normal? I'm 28 weeks pregnant with dd2 and never had this problem at all with dd1.
