34 weeks+4 braxton hicks?

Dull pressure almost period like cramps in the lower abdomen. Are those Braxton hicks? My lower back is hurting so much. It’s affecting my thighs too hence I can’t rlly stand up proper nor walk normally anymore (posture like old woman). On HL and will be going back to work on Monday. Can’t imagine myself sending my kid to CC and then an hr trip each back and forth work taking the public and fetching LO at the end of the day. #justranting
