Uy, mamsh, with placenta previa that heaviness and shortness of breath is really something you need to check with your OB right away, hindi dapat i-ignore yan, lalo na ngayon. Placenta previa talaga can cause different symptoms, pero ang timing at severity ay importante, kaya best na marinig ang expert directly. A few of us moms in the group had pregnancy discomforts, pero when it comes sa placenta previa, ang safe route talaga is to get checked ASAP para ma-rule out kung may concern. Sending you strength, sis, you're doing the right thing by asking!
