My cycle between July and August was 34 days. Glow is saying my next period is due September 14, which will make it 38 days between August and September. My fertile week, according to Glow, starts Wednesday, with my prime day Sunday. Today, though, I have had cramps in my lower back, especially on my lower right side, and my boobs have felt a little tingly and heavy. I am not sure if I am just getting ready to ovulate, or, getting ready to start because my symptoms are the same. If my cycle this time is a little shorter, my fertile period could have started earlier as well, which would mean I could be at the end of it. Please, say a prayer for me or something! I really hope August is my month!! We are not trying in September, so please, please, please let August be it!!!
