Braxton Hicks?!

Veronica
What do BH contractions feel like?! I'm almost 18wk5d and I've been feeling this tightening feeling right above my pelvis. Last night though when I put my feet up on the couch it was pretty intense and uncomfortable. It felt like something was twisting and tightening, and it lasted for maybe a minute. I called the nurses line at my ob and she was so rude and rushed. Told me she didn't know and to just monitor 😩. I'm freaking out!
