Positive strip test

I had a few faint positives, that seemed to be getting darker. Took a test on the 17th, didn’t see anything but the next day I seen a faint line (18th) and then the 19th it looked darker then the day before but still faint. I got a FRER going to take it the next day with FMU but started spotting that night. (19th)

I never spot before, plus I always start in the morning. But I thought maybe it was AF and the strip test were just wrong. But I had bled 2 days and then started spotting again. Which I normally just full on bleed for 5 days, could that have been implantation?? I’m not even doing hardly anything at all now and I should have stopped tomorrow or by Monday.
