It is possible to get pregnant without a period. All that is needed to get pregnant is for the woman to ovulate normally and for the fallopian tubes to be open. The absence of a period is not a requirement for pregnancy, as lactating women have higher than normal levels of prolactin, they may not have a period, but their ovulation is normal and they can become pregnant, so breastfeeding women need to pay attention to contraception in order to avoid pregnancy during breastfeeding. Overall, the necessary conditions for pregnancy include the woman being able to ovulate normally as well as the fallopian tubes being open, and the man and woman having intercourse during the ovulation period, with the man providing sperm with good vitality, so long as the above conditions are met, pregnancy is possible.
