Pano po malaman kung kelan mabubuo ang baby pag irregular ka

Irregular din ako so I used mobile app like Flo. Itrack mo doon ang period mo every month, put all the details like yung vaginal discharge mo for the day then the app will suggest kung kelan ka fertile at mas mataas ang chance mabuntis.

Paultrasound ka malalaman nyo po agad

try searching google sis.. hehe
