Parang may bukol sa breast

Hi momsh. Tanong ko lang if dapat na ba ako mag worry or part talaga ito ng pagbubuntis, kasi sumasakit ang right breast ko sa bandang ilalim at parang may nkakapa akong bukol. Im 33 weeks pregnant not sure kung part ito nang pregnancy or ibang case to na dapat ko ika worry. My OB schedule is not until end of this month. Please advise thanks. #advicepls #advicepls #advicepls #advicepls
