bfn but leaking breasts

Sarah • 👩32, 👧01/14, 👧05/19, 👶09/22 💍 10/19 🇮🇪☘️

can anyone shed some light on this? I'm on cd28 (normally my af time but no sign yet) not sure when I Od this month. but I'm guessing I'm about 14dpo. I took a test this morning that came back bfn.i was super confident that it would he bfp because for the last 4 days I've had moderate cramping and bad lower back pain, neither of these are typical of my pms (my cramping starts the day of af usually). another weird one is my right breast is leaking a cloudy type of fluid, similar to colostrum. Now I stopped breast feeding 4 years ago and nothing has come out of them since!

can anyone help? I feel like I'm going insane 😬
