Period or implantation bleeding?

Period or implantation bleeding?

Okay so basically I ovulated later this month (a few days before my period was due) and had unprotected sex during that time, then i got my period 10 days late, it was brown discharge at first, then spotting pink, then red blood, then some stringy black thing (??idk) and today it was all over (this all happened within 24 hours) now it’s completely gone and this was just all very unusual for me. Also before i got my period i had some weird cramps that weren’t as bad as my period cramps but they lasted a week (which is also weird because i usually get them right before my period starts and they’re way more intense). Now if i am pregnant then the “implantation bleeding” took place about 12 days after conception, which would be 14 days ago. Basically my question is, when should I test? (given this was implantation bleeding and not my period). I stopped bleeding today so how long should i wait? I’m 26 and never been pregnant I’m sorry if this sounds stupid i’m just confused i would also appreciate if anyone who experienced this in their pregnancy could share their experience thank you 💗
