wondering if anyone can help

Christie 💙
I am currently 31w5d pregnant and from around 28 weeks I have been getting really pain where my ovarys are.. I do have polocystic ovarys and as time goes on I am in agony if I sit down for too long and then get up. I barely sleeping at night, as the pain is horrible.. I have a midwife appontment on Monday and I will be telling her about it but I was wondering if anyone else has been through this? And why it is so painful?
