Uy, alam ko scary 'yan, lalo na first time mo. Please go to your doctor or ER agad, hindi ito dapat i-wait, especially with the pain at weakness you're describing. Only your OB can check what's really happening, okay?
You're not overthinking, severe pain sa likod, tiyan, and weakness sa legs kasama ng heavy discharge ay kailangan ng medical check ASAP. Some of my mum friends din nag-panic sa similar symptoms, pero nabigyan sila ng peace of mind once na-check ng doctor. Kahit anong oras yan, punta lang sa nearest hospital, better safe talaga. Sending you love, mama. You did the right thing reaching out.
