Increasing HCG but decrease in Progesterone

On 6/17 my HCG was 262 and progesterone was 34.97. On 6/20 my HCG increased to 1295 but progesterone decreased to 27.35. I’m very nervous about that but my fertility office did not seem worried or even mentioned the progesterone. I saw the results on my portal after they called to schedule an ultrasound next week and to inform me my HCG went up. Is this something I should be worried about? Has anyone else experienced this and everything professed normal?
