Ah mama, kaya nag-worry ka, pero honestly, if you took pills regularly from March 8 to 19, you should have protection pa rin even after you stopped, lalo na if you were consistent those two weeks. That said, the timing from March 19 to April 2-4 is a bit uncertain depending on your cycle, so I'd really suggest getting a pregnancy test or checking in with your OB to put your mind at ease, better safe than sorry, and they can give you the clearest answer based on your actual cycle history. A few of us tried calculating from pill use lang, pero nakakastress talaga, kaya mas good na lang mag-check with your doctor na para ma-confirm mo for sure! Keep us posted pls, and don't stress yourself too much in the meantime.
