aF due today

So my AF was due today and so far no sign of her I have only gotten maybe 2 slight cramps. Usually before I start I start cramping a week before or I don’t cramp at all and I’m ambushed by AF. My sister recently moved in so I’m guessing my cycle got thrown off again since every time I encounter close proximity to other women it changes. And don’t tell me it doesn’t because I know it does since I noticed it after my last job. Anyways here’s to hoping it’s not coming and that we are finally pregnant after a year and 10 months of trying. If not I know I will eventually have my turn and if not their is always adoption.
