Probably implanted on 7dpo

It had a tense feeling in my lower abdomen. It was also a pinching and pulling feeling and still feels tense there. I felt so dizzy and lightheaded all day and fatigue like crazy. That day I had a big temp drop and a spike the next morning. Now I’m 8/9dpo. Who else experienced this and ended up pregnant ? :) I’m more sure that it was implantation than not.
