Dec. 03 should be the start of my period kaso wala. Dec. 07, I had dark brown vaginal discharge. Wala pang 1 teaspoon siguro yung lumabas. Konti lang. Dec. 8-9, parang regla naman na yung lumbas na dugo, madami. Siguro nakakapuno ako ng 4 pads sa isang araw. Dec. 10-12, light bleeding na lang. Dec. 13-15, light brown discharge. I took pregancy test(early morning)..
