ovarian cysts

✨sav ✨
I've been putting off going to the doctor for so long but I finally went 2 days ago.
Anyway I have a lump in my stomach which in the past few months has been getting bigger and bigger, it feels like I have a ball in there.
The doctor has sent an urgent referral for me to get an ultra sound but could still take up to 6 months to happen (unless I pay $250 to get it done privately but I'm too poor for that) but he told me best case is it's an ovarian cyst, worst case it's a tumour that could be/become cancerous. 
He also said that if he didn't know better he'd think I was 6-7 months pregnant, that's how big this things is 😢
Anyway I wanted to see if anyone else had dealt with something like this before? I'm really freaked out and stressed about it. 
Thanks
