I got BH all through my pregnancy with DS and i've been getting them during this pregnancy since about 11 weeks! They just feel like a tightening/hardness in and around my bump and sometimes its a bit uncomfortable to move if i have one. If you look at your tummy when you're having one it'll probably be sticking out at a weird angle or be a bit weird shaped. I get them all the time- at least 5-6 a day and especially whenever i need to wee. Its all normal and nothing to worry about. My OB said the reason i get them so often is because i'm so busy running around after a toddler Just think of it as a sign that your body knows what to do and is getting ready for the big day!
