Please reply, im scared

Recently I've been having pain my left ovary and sometimes my entire lower abdomen, I've also been experiencing bloating and constipation and my discharge has been more frequent, thicker and a bit white. Two months ago I've found a tiny lump on the inside of my vag right next to my cervix. It is a small lump, unmovable and does not hurt while applied pressure to. I am waiting for my gynecologist appointment, but does anyone have any idea what that might be?
