What the hell is going on?!?

Almost a week ago I was told I had a chemical pregnancy doctor wanted to run a few more tests which the results left him confused he says I could still be pregnant never was or chemical pregnancy but if I never was how come I had 8 positive hpt over a period of time. He ran more tests no hcg but still a faint hpt fainter then previous ones. He wants me back in a week again for another blood test what the hell is going on in trying to hold my stuff together for my daughter but I'm so frustrated!!!
