Braxton hicks advice please

K
I'm 33 weeks pregnant with my second. With my first I didn't experience braxton hicks or maybe just didn't notice them. I'm asking is it normal to have quite frequent braxton hicks there not painful just feels uncomfortable makes me hot and my belly goes really hard for maybe 30 seconds or less.. My midwife app last week also said that my baby was in breach position is this also causing more discomfort when pressure is put on my belly tia x
