Pregnant?

Ok so we have been TTC for the past 5 years. I have two children and he has 4 from a devious marriage. Initially I was told my tunes naturally closed and chances to naturally conceive are zero to none. I've been tracking my periods since May last year. Long story short... My period is due next week, we BD every other day ( no matter if it's the fertile day or not) I've been having an elevated temperature for the past few days (feeling healthy, so no cold etc) ranging from 99.8 to 100.5, I have a different kind than normal cramping and no spotting.... Could this be a miracle????
