Currently 28 wks, prior to pregnancy had 2 cyst ruptures. When I became pregnant I had a 3cm cyst in left ovary. No mention of it was made again until 20 week anatomy scan when it appeared to have grown to 6cm. Fetal specialist Dr became alarmed and sent me for MRI (which I am still not totally convinced was appropriate). Results showed 7-8cm complex cyst that was hemorrhaging. Oncologist said it's very common for pre-existing cysts to grow during pregnancy because of hormones. And that it only becomes problematic when it gets much larger (10+) because of risk of it cutting of blood supply. She wasn't concerned. Long story short, when I went back to have ultrasound to check cyst around 24 weeks, it hadn't grown. Just went for 28 week ultrasound and there is no evidence of cyst (could be because the ovary is hard to completely view at this point, or because cyst resolved itself, or shrunk) . Dr is confident cyst at the very least hasn't grown, and most likely shrunk, and she said its very common for cysts to resolve themselves during pregnancy and after. My understanding after meeting with oncologist and speaking with my Drs, is It's very common for common for cysts to grow or develop during pregnancy because of the fluctuating hormones. Usually they resolve themselves, or stabilize after certain point of growth. I hope this helps! </p> https://boards.hellobee.com/topic/any-experience-with-cysts-developing-later-in-pregnancy-20-weeks#post-2276028 Fri, 28 Aug 2015 13:52:15 +0000 MaryM 2276028@https://boards.hellobee.com/ <p>I've had a history of ovarian cysts, but early in my pregnancy we were relieved that they all seemed to have resolved. I did have a small corpus luteum cyst on my right ovary, but it was nothing compared to the 5-9cm cysts I'd had while TTC</p> <p>Well now at my 20 week scan (last scan was at 12 weeks and was clear), they discovered a 6 cm cyst on my left ovary. So it's definitely NOT the CL. </p> <p>I'm concerned mostly with what caused it because my hormones should be level and NOT like those of a menstruating woman (which they blamed previous cysts on). They're watching it so I go back in 3 weeks for a follow up. </p> <p>My old cysts got up to 9 cm and resolved themselves, but with a growing uterus, this sounds a lot more scary. </p> <p>Any experience/advice?? </p>
