swollen cervix??

Michela
3 & 1/2 weeks ago I had some white discharge and I stuck my finger up my vagina to see if there was a lot of disachrge or not. For a sec I thought something was inside my vagina that I wasn't aware of (!) but then I realized that my cervix was the size of a golf ball! I continued checking it for several days and after about 5 days it went down a lot but for the past 3 weeks it's been in a weird long shape. Like 1/3 of a hot dog and it's a little hard. There's been no pain but I've never noticed my cervix till this. Is this normal and does anyone know what it might be/what caused it? I haven't had any abnormal discharge or bad smell and my period came and went and it's still like this.
