So frustrated! Needing advice!

Okay ladies! I'm in need of some advice, stories from what has happened to you, or whatever you may have you want to share!! My period was due today! Still No AF! Yah! That's amazing I know! But took a test and BFN! (Horrible). 2 days ago I had a thick milky discharge that lasted for a couple of days! Horrible back pain, super tired, and my face has really dry patches on it now where my face was completely clear before! Can anyone help out with what they think?! Prego  maybe? Or no because the BFN! Thanks ladies!!
