Okay guys help! My period is now 3 days late. No sign of AF and my discharge has basically been the same since 10dpo (white and creamy). I've had tons of symptoms; nausea , bloating , headaches , lower back pain, twinges in my right & left ovaries in assuming, pulling and pinching behind my belly button, darkening linea nigra , swollen boobs that now possess stretch marks, frequent urination. I haven't tested since 14dpo and it was bfn that day. I'm 17dpo now and still no AF. Possibly pregnant?
