Ask ko lang po. Okay lang ba magpaglaw kahit buntis ? 11wks

Hello, My last day of menstruation was January 27, until this February na hindi ako dinatnan but I wasn't bothered kasi irregular ako like sa isang taon 3 beses lang akong datnan. This past week, nagkasakit ako 4days pong sumakit katawan, ulo, balakang, puson at tyan ko akala ko dahil sa UTI. Lagi rin sumsakit ulo ko, having mood swings I never thought I am preggy kasi irreg ako, until I take PT last last day and it was tested positive. I want to know if this is really confirmed based on your experiences po. Do I have to PT po again? Ty please respect po. I'm 22 yrs old and a first time mom
