AF due tomorrow....

Did everything right this month. Lots of BDing during (also before and after lol) fertile week with preseed and +OPK
Weird metallic taste in mouth for about a week now, super sore boobs, nipples feel bruised almost (aren't tho), super tired and emotional, hips and back are killing me. I have a puffy lower belly. I know most of those are/can be symptoms for both pms and being prego. I usually just get cramps and sore boobs. I tested early with BPN. The anticipation is driving me nuts!!! 
Does anyone else go bananas right before their Af?
Also my cycle is only 24 days, would this affect timing of a BFP
