Mamsh, brown discharge at 35 weeks can be normal, pero since it just started today and you're not sure, please call or text your OB right away, hindi mo na kailangang maghintay for your next appointment. Better safe than sorry sa ganitong stage ng pregnancy, talaga! A few of us moms had similar worries, and our doctors said that sometimes it's just from the cervix or internal exam, pero they always wanted to check it out agad para ma-rule out anything else. Since you're at a public hospital, they usually have a hotline or you can go to the ER if you can't reach your doctor, walang hassle, free naman sa public health. Keep an eye din kung may other signs like cramping, bleeding, or spotting, if meron, go na ngayon. You're so close to delivery na, mamsh, better to get peace of mind!
