I don’t know anymore

So about a month ago I was diagnosed with a 2 cm complex cyst on my right ovary. My gyno said to do a follow up transvaginal ultrasound in 4-6 weeks. Yesterday I went in for the transvaginal ultrasound and was told the right ovary contained no mass or anything. But I’m still in pain on the right side like it is still there. I’m confused 😕 I was told I have a simple cyst on the left ovary. Not sure why I’m still having pain on right ovary.
