Does anyone get this BEFORE their period ? Or is it a sign of IMPLANTATION ?!

Not due for another 4-6 days . I’ve been feeling off since Feb 11 and I ovulated the 11th or 15th ! I woke up to this and have been crampy since the 11th and sore nipples since the 11th .

I’ve been testing since Saturday and swore I had a vfl yesterday morning but idk .
