Got my positive OPK!

Terre • Married to my high school sweet heart. 8/3/13. ❤️TTC #1 since August.
Just took my OPk and got a wayy positive! According to glow today is my first fertile day and thank goodness I was testing otherwise I might have missed it! We bd on Monday and will tonight. I took mucinex today and will use preseed internally tonight. (Even though I think I have a weird reaction to it causing uti symptoms). Praying this is it! How is everyone else doing!?
