hi, just want to check that this is normal

i have been having alot of cramping, almost like pressure on my pelvic bone and excessive "clumps" of CM. Maybe teaspoon full's at a time and its constant.

Going from my last pregnancy, it almost looks like my plug - thats the thickness and consistancy of it.

Do you think i need to be checked out? or is this fairly normal?
Also i am getting alot of dizzy spells, to the point where i feel like i am falling off my chair and i have to hold onto something.
