Cyst on Ovary during pregnancy

I found out I was pregnant on the 1st of August and I had my ultrasound today to check on my baby. While checking the doctors looked and seen I have a cyst and the doctor told me that was normal but he just seemed annoyed with the questions I was asking. Have any of you mommy’s had a cyst on your ovary while pregnant? Is it dangerous for the baby or pregnancy? Is it normal or something I should me worried about? And also the doctor suggested I get a sugar test on the 22nd but I’ll be 9 weeks then.... is that to early to be taking that test?
