Dilation?? Have you attempted to check? 37+4 cramping and some lower back pain

So I've made it to may. Yaay! No worries on preterm labor. But I went to see my midwife last week and she checked me and said I wasn't dilating yet but my cervix is very soft. I thought to myself either I am going through these symptoms for fun or she just don't know what she's talking about. 😒 I decided to check for myself. Of course I cleaned my hands very well and followed proper procedure. I read where if you're able to put a finger or two or more into the cervix then dilation has begun. I am able to fit a finger in without any problems. Wondering how many cm I have reached now?
