Cramping

Amy
34 weeks tomorrow and I'm having strong menstrual-type cramps that won't seem to go away! Have had plenty of fluids and resting on left side but still having the cramps as well as low back pain. Is this what Braxton-Hicks feel like? I've had other instances in which my belly gets very tight, but not painful, and thought those were more likely BH contractions. I'm a FTM so pretty clueless 😊
