I'm 12dpo today, I've took a pregnancy test and it was negative.

But I've been checking my cervix everyday. And today (which is usually when it becomes firm and low because period is due in a day or 2.), its medium height and soft. And I feel wetter down there.

I've been having cramps and God awful backaches.

I don't wanna seem too positive but I think I could be pregnant. And maybe the Hcg just isn't high enough for it to be detected yet. It's just this month really feels different. I feel like my insides are being stretch. Not to mention the nausea. I woke up this morning at 5am feeling so dizzy. The nausea started last night..

And to be honest, my boobs are kinda big so I can't tell a difference if it became fuller or not but its definitely more sore at the sides..

Is it possible that I am pregnant? Or does the BFN just mean I'm not pregnant and it's just AF coming?
