Hi mama! Implants are super effective, kung inilagay nang tama at walang problema, very rare talaga ang chance ng pagbubuntis, pero it's not 100% guaranteed kaya may tiny possibility pa rin. I'd really suggest asking your OB directly about this kasi sila ang best person to explain kung paano exactly gumagana sa'yo, and they can check din if it's still properly positioned! A few of us tried different methods and sobrang importante talaga na masigurado ka sa doctor mismo, especially since first-time ka pa lang.
