cervix question

I'm new to this. I just tried it for the first time and it feels high and firm with a little bit of a discharge. I can't tell if it's white or clear yet. But my question is when I touched my cervix it gave me cramps? Is this normal?
AF is due 1/16. My guy came in me January 1st. I've had cramps off and on for about 5 days. Very sore breasts and swollen lymph nodes. Nauseous off and on but not bad. Headaches and backaches (I also have ddd). I've been super tired more then normal and hungrier then normal. I normally don't eat much or anything at all close to when I start and during. Pain during sex and after orgasm. I am just starting to ttc so I have no idea lol.
