Symptoms?

Kirsty
Hello
So I am 12 dpo and AF is due in 2 days, I have been having slight cramps which I only get whilst af is here and have been getting bad headaches most evenings, also breaking out in spots all over my face which never happens also have noticed that my boobs seem bigger and my nipples are really sensitive. I tested on the 5th+6th and got bfn and I know it was to early. Just curious could this be pregnancy symptoms? What symptoms did you get when you were first pregnant? Thanks ladies!xx
