I've been getting bad Braxton Hicks on and off since yesterday - not regular at all, well maybe every 10 minutes for about an hr then nothing. My whole tummy and back goes tight, especially the top, but at the same time I feel like I'm suddenly really tight chested and can't breath. In fact that's the most uncomfortable bit of it. I have to lean over something to open my chest up. I didn't have any BH with my 1st son, and didn't go into labour with him either so I have no idea. I also woke up this morning and threw up for the first time this pregnancy (luck cow I know). Does this seem right to anyone?
