Good sign of pregnancy or not!!!

Hey ladies I'm currently 12dpo and my vaginal walls are so tight and swollen that I can't measure my cervix or barely get one finger up there. I've been taking my prenatal vits and my progesterone as usual and I got a neg ov test and preg test today. I dnt know what to think to make of everything...have any of you ladies had this happen and still got a BFP?
