Hoping this is my month🤞🏻🤞🏻

So I start my prescription for BV today... my fiancé comes home sunday(he travels for work) & my fertile window starts in 5 days... which means my prescription will be done 2 days into my fertile window.. do y’all think I still have a chance of this being my month??😇🙏🏻🤞🏻
