Assuming I’m pregnant 🤷‍♀️

Ok so I’m assuming that I’m pregnant bc I had supposedly protected sex on June the 15 two weeks later I started bleeding 3 days before my due period I started bleeding again about 3 and a half weeks later I supposed to have a period tomorrow but I’m not really feeling any signs of it I woke up this morning feeling wet down there for some reason it wasn’t pee tho it looked like it have a little brown mixed in I also started spotting 9 days ago of brown little specks you could barely see it only when I wipe most ppl on here told me they had that when they were pregnant I really don’t know what to I’m worried
