I don’t think bukol is a normal part of pregnancy. If there’s a chance na bukol nga ito, please have it checked. Pwede mo sya i text muna yung OB mo if that’s an option pero kung wala kamg direct na contact, at nag aalala ka na, pwede ka po magpadala na sa ER muna baka they will give test or imaging studies to check kung ano po yung nakakapa nyo. Then just present it to your OB once you have your consult with her.
