I am 15 DPO, my period is irregular so the P.D. App says it should've been here on the 10th, Glow says the 14th, and Ovia says the 15th. I don't want to test too early because I'm afraid of getting a BFN and then getting discouraged. My nipples have been sore on and off, I've been having slight cramping in my pelvic area and stomach for a week now and have also been constipated with almost no appetite-which is kind of unusual for me because before AF I'm usually eating everything lol. Any advice welcome.
