9dpo and a bfn

I know it's too early to test but I O'd early this month bc my period only lasted 2 days. So I thought maybe just maybe I could get a bfp but no. I am going out dancing tonight to celebrate my birthday so I plan on drinking a little since I feel out even though I may not be. I feel sad. This is month 8 ttc #1 and I'm about totally over it. Lol. And the stress and quitting my adhd meds have made me gain 10lbs which really isn't helping my mental status! Anyone else have weight gain during ttc for no reason? I eat healthy and small portions, no soda, work out and everything! Sigh.
