<s>[INST] I had sex with my girl friend while her periods...i.e on 5th day.....does she can become pregnant .....If so also....tell me natural way...How to abort it........ [/INST] Hi, thanks for query.  Sex during period can cause pregnancy reasons are- 1)sperm can survive for up to 5 days in vagina and if ovulation occur early as 10th day chances of pregnancy there.  2)if it is not a period, but it is ovulation bleeding chances of pregnancy is there.  3)if her period is irregular time of ovulation not fixed, chances of pregnancy is there.  4)delayed period and early ovulation can cause pregnancy.  5)take emergency contraceptive as early as 72hrs.  6)always use condom.  don't worry, if period not come consult gone.  GOOD LUCK. </s>
