Weird smell!

So I woke up this morning smelling rubbing alcohol! The smell is so strong but no one else in my house is smelling it but me! My hubby and I have been trying to get pregnant for 5 years and nothing... <a href="">Eve</a> said I'm supposed to be getting my period on the 8th last month I started on the 11th and i still haven't started my period! Usually I cramp horribly about a week before and then I start but lately I've been having tiny cramps, sore breasts, my nipples are so hard that you can see them through my bra and shirt! These are all of my period symptoms except the minor cramps and hard nipples! Anyone else experience this before their period? I don't wanna think I'm pregnant because it gets my hopes up and I always get let down. Advice anyone?
