Simple cyst

On New Year’s eve I was checked at the ER for a UTI I apparently had I did not know about in the process they did an ultrasound and found a 2cm cyst on my left ovary. I was checked by my gyn Jan 2 and the cyst was still 2 cm. This past Wednesday they checked due to pain I was having and found it’s now 4.3cm and has a separation to it. Can this dissolve in its own or will this grow in size? Will it burst or need to be removed. This the second cyst I’ve dealt with I’ve known about. My first one was removed in 2018.
