Ovulation

Lexy

So guys my fiancé and I have been trying to get pregnant for the past four months... Monday the 15th I had clear stretchy cervical mucus and a lot of it... I was supposed to start my period today but I never started... I have NEVER had clear stretchy cervical mucus this late in my cycle! I have taken multiple pregnancy tests and all have come back negative.... so two questions... 1 is it normal/possible to ovulate 8 days before a period..2 is it possible to even get pregnant 8 days before a period?!?
