Negative HCG but high Progesterone??? Please help

Lila

We did <a href="https://glowing.com/glow-fertility-program">IUI</a> on 03-21. And yesterday i went in for bw because i couldnt wait. My ob just called and said HCG was negative but Progesterone was high. And he said i should wait to see if i miss my period. Has this ever happen to anyone. Is there any chance that it was too early even for blood work. Any chance of baby??
