Can someone please tell me what’s going on?

So I’ve gotten several positive pregnancy tests the last couple days well I started bleeding a little not know to even get any on a pad or anything and now I’ve stopped bleeding and it had a ton of mucus in it (sorry for the TMI) it was never heavy bleeding. Anyway, I went any had my HCG blood test done today and it came back negative?? (WHAT IN THE WORLD) and I got another positive test this morning. So, I don’t understand this at all??? Can’t anyone tell me what’s going on or happening??? I’m a nervous wreck and don’t get it and been emotional because back in January I lost my precious baby boy at almost 24 weeks he was born sleeping 💔😢. If anyone could help me I would greatly appreciate it so much!! Has anyone had this happen to them and tell me anything??? Thank you I greatly appreciate it. I’ll post pictures of the positive pregnancy tests I’ve gotten and my HCG blood test results!!
