Can you get pregnant two days before period? whatre the chances?

Generally, no: Women get pregnant about 14 days before the day that the NEXT menstrual period is supposed to come... and if pregnant, that day actually won't come for another 10 months or so, after a cute little baby is born. Guessing days leads to pregnancy, so a woman trying not to get pregnant needs to have a reliable form of birth control all the time.

Yes: Pregnancy has been documented from unprotected exposure on any day of a woman's cycle including during menses. It is rare, but when it happens it is more likely among the irregular. Your cycle may be a estrogen breakdown cycle after a missed ovulation (makes you irregular). You could then ovulate and be ready to conceive at any point.
