Ok it’s weird

I’m 5dpo and I’ve been having so much cramping and HEADACHES like it’s TERRIBLE!! I normally don’t have headaches. I ’ve even had a butt ton of CM (see pic) which is white and I don’t know if I am pregnant—yet. I had sex on the 12th and I ovulated on the 12th so idk if I am or not.

I wiped this morning and this happened.

It is a lot and varied in color and consistency throughout today. My only problem is that I’ve never had this much in any cycle ever. So it would be helpful if you could tell me what’s going on and if I need to test.
