Ovarian cyst no response to sysron-n.

I had ivf egg pick up on Dec 13, 2023. I got period on Dec 17, 2023. In order to plan for frozen embryo transfer the Dr has put me on sysron-n 5mg (2 tablets per day) from Jan 13, as there is corpus letum cyst and 2 other functional cysts in the right ovary. My left ovary was removed due to torsion in 2008. The ultrasound scan done on Jan 22 showed one cyst of 13mm. So the Dr has asked to continue sysron-n for 5 more days. The ultrasound scan done on Jan 27 showed the cyst size as 14mm. Sysron was continued for 10 more days and ultrasound scan done on Feb 6th showed the size of cyst as 16mm. Why is the cyst increasing 1mm per 5days instead of decreasing for sysron-n? The Dr has asked to stop sysron-n from Feb 6th. Will the cyst dissolve during mensuration or will it further increase in size?
