Frequent Brixton Hicks at 32 weeks

Hi Mummies, have you ever experienced frequent Brixton hicks contractions? I’m currently in 32 weeks and have been experiencing BH contractions every half an hour. It has been going on over a week already. They are mild and bearable. I know BH contractions are normal during the third trimester but isn’t it too frequent to have it every half and hour or so?
