Implantation bleeding?

So, on the 28th my fiance had sex, TTC. And, I felt a little off since then. We thsn had sex again on the 1st using pre-seed. This past week I have been on my fertile window. PRAYING to become pregnant. Well this morning I woke up to go pee and i had light pink when I wiped. So i went to the store and bought a FRER test. I took it, and when I wiped there was light brown. Within the time frame, there was a vvvvvfl and I dont know if i should test again first thing tomorrow morning, or wait for ny period on the 14th to retest. Any opinions? 😇😊
