Ay, mama, swelling or lumps sa underarm area during pregnancy ay kailangan talaga i-check ng doctor, please don't wait on this one, okay? It's better to get it cleared up soon para sa peace of mind mo. A few of us moms have had similar scares, and once checked, it turned out to be nothing serious, pero importante talaga makita ng professional, lalo na ngayon na buntis ka pa. Kaya go ahead and book an appointment with your OB or dermatologist ha, walang masama sa pag-alam mo exactly what's going on. Sending you love, mama!
