Please need answers. Fluid in pelvic area

Ok so I’ve been having cramps and feeling nauseous here and there and I went to the doctors and found out it was my fibroids acting up again and was told I had fluid in my pelvic. I never heard this before. I have a follow up with my doctor this week coming up but I was wondering has anyone else had the problem before. Please don’t read and not respond. Need answers thank you.
