Can I get pregnant while on my period?

It is very unlikely that you will get pregnant if you have sexual intercourse during your menstrual period as this is really not your fertile time of the month. Even if you have ovulated during your fertile period, this would have happened much earlier and the egg would not be able to survive till this time (the egg only survives for 24 hours post-ovulation if not fertilized by sperm). Concurrently as you are having your menses, the endometrium (lining of the womb) is shed so this would make it impossible for implantation of the embryo to occur and therefore pregnancy.
