Do I need to re test or leave it?

Hi so I believe I am experiencing a chemical pregnancy, hasn’t been confirmed or anything but I had 4 faint positive tests that never got any darker then started my period 4 days later.

I never really knew anything about them and I guess I never would have even known if I didnt test I would of just thought my period was late as that isn’t unusual for me.

This AF is different to usual ones, it’s really quite dark but not heavy at all (probably only filling one pad a day) but I have had quite harsh period pains (again usual for me)

I was just wondering if I need to retest after my period or anything? Or if I just leave it and carry on TTC?

Just feeling a little all over the place about it and any advice would be really appreciated

Thank you
