Sexo desprotegido durante o período seguro – a gravidez ainda pode acontecer?

Yes, pregnancy can still occur during the so-called “safe period,” especially if cycles are irregular. Ovulation timing can vary due to stress, illness, or hormonal fluctuations. Sperm can survive in the reproductive tract for up to five days, increasing the possibility of fertilization if ovulation occurs earlier than expected. The calendar method is not fully reliable for contraception. If concerned, consider pregnancy testing or emergency contraception within the recommended timeframe.
