Strong Cramps. Constipation. Yellowish CM.

Hey y'all. I'm really confused. I'm having the strongest cramps ever the past 48 - 72 hours with constipation, and tiredness. The only time I had sex during my fertile window was exactly 7 days ago. It's too early to test as AF isn't due until 1/14. Does anyone have ideas? I NEVER cramp before a period, and if I do, it's literally because I'm starting. I've had a yellowish tinge looking CM but that was last night. No CM tonight. Grr. Bodies.
