Uy, mama, hindi ito basta-basta, please go to your OB or emergency room na ngayon para ma-check agad, especially with the cramping and discharge na yan. Hindi dapat mag-antay pa, okay? Brown discharge with a week delayed period at ganyang severe pain could be maraming reasons, pero kailangan talaga ng proper checkup para malaman kung ano exactly ang nangyayari. A few of us moms here in the group have learned the hard way na these things need to be checked right away, mas peace of mind ka kung alam mo exactly ano ang situation. Take care, and keep us posted, ha?
