Help ??🤷‍♀️🤷‍♀️🤷‍♀️

Hey girls basically I just wanna ask you all something because I have no clue what’s going on ok so basically on the 17th I had a faint positive but later on that day I wiped and there was blood then it went tested a few more times faint positives but nothing like a a bfp anyways 2 days ago I wiped and there was blood again it was red then went to pink then to how it looks when it’s old blood since Ben I’ve had nothing in also 3 days late for my period which is weird as AF is normally on time my boobs are bloody sore and feel really heavy which is weird my question is could I be pregnant? Because the lines haven’t got darker I took a opk on the 9th which was positive but I dunno I could of ovulated late or I dunno could it be a chemical? The only thing I’ve realised is that my boobs are sore and I’m constantly tired please any comments would be appreciate prg
