Uy mama, any lump or swelling sa breast during pregnancy ay kailangan tingnan ng doctor right away, hindi ito something to wait out, especially para sa peace of mind mo. Please make an appointment with your OB or dermatologist soon, okay? Marami sa amin nag-worry din about these things during pregnancy, pero better safe than sorry talaga, at sige lang sila sa pregnancy check-ups anyway. Keep an eye on it in the meantime, if it gets painful, hot, or may pus, go to ER na agad. You've got this, mama!
