BFN, but praying for BFP! ??✨❤️

Zuly • Never stop trying!
Tested today and got a BFN. A little bit of background info on why o tested: I have been irregular with my period for the past year or more. Recently changed GYN and she put me on (Progresterone, which is also known as Prometrium). I am supposed to take 1 pill everyday for 12 days. Well this pill has been working and has given me my period religiously for the past 3 months. This month, November I DID NOT get a period and currently am on day 7, going on day 8 which makes me 7 days late on my period. I have been experiencing symptoms such as moodiness, extreme tender breasts, emotional, & decreased appetite. I tested today 11/30 and got this result. When should I test again, if I should anyway?
