can a girl get prgnant on her period?.........even though the guys penis wasnt absouloutly erect?

Hi Megan,

Possibly.  It all depends upon when you ovulate? 

Normally, on a 28 day cycle, you'd ovulate between days 11-16.  Sperm can remain viable for up to 5 days.  So, if your period lasts more than 6 days or so, then, yes.

Hope it helps.
