When I first found out I was pregnant I had a lot of pain on my left side, they suspected ectopic but after a few scans they ruled this out and found a cyst on the left. They told me it shouldn't cause any problems or pain however it does especially when my bladder is full! I went for a scan at 12 weeks and the cyst is still there it hasn't shrunk at all and the midwife said she can't believe how big it is, measuring at around 7 cm. Has anyone else ever had issues with this and what happened with it? Thank you :)
