Have you experienced this?

Has anyone had positive pregnancy tests but also getting negative ones? I had sex on September 13-15 I’ve been have symptoms and I’ve gotten positive tests but I’ve also gotten negative tests so I’m super confused as to what I’m the world is going on. Could I actually be pregnant?

Here are two of the positives I’ve had 6 positives but also negatives too. Is it possible I still need more hcg?
