Day #2 of missed period! Help

Okay so today is day number two of missed period. I got off the pill in early December and immediately had 2 regular cycles. They have always been regular and I even got pregnant ON birth control with my daughter 6 years ago (missed a couple days) My husband and I have been trying for #2 since I got off in December. My OV days and fertile days vary from each app and I’ve never tried to track before this. However, my nipples have been consistently erect and EXTREMELY ITCHY and tingly ALL the time!! It doesn’t matter what position/hot or cold etc but they aren’t particularly sore? I’ve had other symptoms too but this is the only one I CANT mistake for pms symptom. I tested 5 days before missed period and got BFN I also tested 3 days before and also BFN. AF was supposed to start on the 8th and so far nothing... nervous to test again because I know they say the tests are pretty accurate that soon before missed period, also it can’t be that common to get pregnant that fast after coming off bcp right? Don’t want to get my hopes up Ahhhhh help!
