Buntis po ba ako?

Good day po maam tanong ko lang po nagtalik po kami ng kasintaha ko January 3 2024 (that day ovulation sya) withdrawal method po. Pag january 15 nmn po niregla na sya as in regla po from january 15-21 , 2024. And then from january 21-february 7 2024 wala pong nagyari sa amin. February 8-13 niregla na naman po sya (bali from january 21-feb.8, 2 weeks lng po ang pagitan) buntis po ba sya? Maraming salamat sa sagot🙏
