Possible po bang buntid ako?

Hi po. Regular po cycle ko, ma-delay man either 1-2 days lang, then it would lasts mga 7-8days long. Last December 20, I had my period, pero nag last lang sya ng 3-4 days tapos biglang nawala. Then, January 9, while taking a bath, may lumabas pong milky white with a tiny blood po. Then lately, I have no appetite, minsan pinipilit ko na lang kumain, but everytime I do, naduduwal ako and hilong hilo nako, almost kalahati ng araw ko. Am I pregnant? Thanks po!
