Do you notice that some situations make them worse than others? I'm fairly certain that my BH contractions have morphed into prelabor. I'm having about 6-10 contractions a day, so nothing to worry about yet, but I have noticed it's a lot worse if I have to go to the bathroom, when I'm really full, or when I just stand up. Has anyone else noticed this? Maybe it's just coincidence (although I have heard of having a full bladder causing contractions before).
