What’s goings on?!?

According to glow I ovulated around the 20-25 of September. Around what I believe to be 12 dpo I experienced spotting only when I wiped & this only lasted a few hours. I took a test the next day ( 13 dpo) and it was negative. I believe this could’ve been implantation bleeding & now I know it takes a few days for the hormone to build up . Other than light cramps and the spotting I haven’t gotten any other symptoms I could be pregnant. I know the only way to know is to test again but I just want to know if anyone else went through this with no symptoms & still been pregnant? My period was due on the 8th but it’s late & im irregular so it’s hard for me to know . The spotting through me off so just wondering what you all think?!
