back ache at 14 weeks

hello mummies! i’ve been experiencing back pain since the end of week 12 of pregnancy, i’m at maybe 14 weeks now, is this normal? cause previously i had back pain too but was a miscarriage :( kind of worried and overthinking now. next appt is next week, should i wait for the appt and tell the doc abt the back ache? #concern #newmom #adviceplease #14weeks
