Perinatologist ultrasound

Marissa
I am currently 26 weeks and have been going to the perinatologist for ultrasounds every few weeks since my 18 week anatomy scan. They found a cyst early on and have been keeping an eye on it (reason for the follow up scans). My husband and I declined all first trimester screenings for several reasons. Today I went in for a scan which seemed to take a while and they took alot of measurements, doc came in said everything looks great and he booked me for another scan in 6 weeks. I can't shake the feeling that they saw something but aren't telling me. So here is my question...if I declined first tri screening does that mean they won't tell me if they find any abnormalities on future ultrasounds? I feel crazy for even asking but I just wanted to see if anyone else had been through anything similar
