11DPO and bad backache

TW

I had a chemical back in September and I had regular period last month and I’m pretty sure I ovulated I mean we were like rabbits all month.

And I really don’t mean to symptom check, but my back is killing me right at the lower back/tailbone. And I’ve had what seems to be lightening crotch over the weekend (super weird feeling) a little crampy but not too bad. I did take a test this morning with a vvvvfl but idk maybe line eyes too. Went into it thinking it would be negative

Sooo moral of the story either I’m gonna have a crappy period here in the next couples days (I’m due for AF the 11th) or I’m pregnant anyone experienced this and get their BFP ?
