Ay alam ko yan worry mo, pero honestly ang best person to ask talaga is your OB kasi sila ang makikita ng buong picture ng myoma mo at kung paano siya positioned sa pregnancy mo. A few of us moms here had fibroids din during pregnancy, and bawat case talaga is different, some were totally fine throughout, pero need mo talaga ng doctor's reassurance kasi that's the only way you'll really rest easy at 15 weeks pa lang. Para sa peace of mind mo, maybe ask your OB sa next visit specifically kung may risk ba or kung kailangan ng close monitoring lang, okay?
