spotting and pain

had my PT last saturday and went positive. worry ko now is napansin ko may spotting ako, just today lng since after we found out i'm preggy. also, masakit tiyan ko kanina umaga pag gising. wla pa schedule ng checkup kase waiting pa ko for my OB from vacation leave. meron ba naka experience ng the same? ano ibig sabihin?#pleasehelp
