Well, condoms breaking CAN lead to pregnancy. However, luck may be on your side here as that is not a regular time that women get pregnant. Once most women ovulate, they can not get pregnant until the next cycle unless they are that one in a million who has a second egg. OR they are just spotting, having an off cycle and ovulation is still or about to occur. Anyway, I doubt you got pregnant from this if it was truly your period. good luck
