Hello everyone I havent found anyone with the same experience as me so I thought I'd post to get your experience and thoughts. I'm currently 17 weeks but at 15 weeks during an ultrasound a fluid filled cyst/sack( they're not sure yet) was found on the side of my baby's neck. I have had a normal/low risk nipt and am only a carrier of sickle disease. So my question is has anyone had abnormal finding on an ultrasound like this and what answers have you been given about it?

P.s I have a mfm appointment next month and normal check in with my ob every 3 week. I just need somewhere to start to keep my mind from wondering
