Help!

I had an iui done and had my blood test Monday. It came back postive. (Dr said extremely postive) progesterone was low so he upped them meds and I went back this morning to check that. Dr called this evening and said progesterone went up. Hcg detected was 0!!! He said he doesn't have an answer and doesn't know what's going on so they are re calibrating there machine and said to come back Friday to re test.
Here is the weird part...
When my blood from this morning came back neg he had them run the sample from Monday and that came back neg also when it came back extremely positive Monday!!! I'm so confused and upset and hurt and idk what to think! Please any advice??
