Maybe maybe not?

Today is dpo12 Iv been nauseous and faint and my skin is oily and breaking out. Had creamy cm! Af supposed to start in 3 days... Decided to test this morning and I got a positive! After my 3rd morning wee so I'm guessing that's correct. Had a huge glass of water and tested with a different brand and got a negative?? So confused! So I went for blood tests and I'm waiting for the results now! Hoping it's a positive!!
