Could it be early pregnancy?

My period is due in 2 days. Yesterday i checked my cervix and it was high and a bit firm consistency, and today it is high and soft. And i am having watery discharge, like it has increased since yesterday, i thought i was getting my period. But it was just the discharge. My breasts are bigger and sore from last 11 days. But since today morning they are extra sore like i am sitting on the sofa and they are just hurting from the inside. I do get sore boobs before my periods but not this much. Took a pregnancy test this morning and it was a BFN. I don’t know i am just driving myself crazy with all these symptoms. I have miscarried twice before 😞
