Mag PT po. On my case, 4days missed period palang nag pt na ako then positive na. Masakit yung boobs ko parang namamaga. Yun lang yung naramdaman ko parang same ng feeling bago magka period.
if hindi nadedelay ng ganyang katagal, try po magpt. as for signs, iba iba po. some experience it some don't except for missed period.
