Implantation bleeding?

Hey everyone... my husband and I have been TTC for 3 years with 1 MC... I am currently CD22... earlier today I had some cramping, it felt like it was more in my ovary but def felt weird down there... I never get pregnant so I just chalked it up to nothing. My husband and I had sex tonight and when I was cleaning up I noticed a dark brown blood tinged stain.. I would be 7DPO.. did anyone’s implantation bleeding look like this???

Trying not to get hopeful but this is my LAST cycle before starting IVF and not having to do that would be a dream...
