Maybe ⁉️

My AF is 3 days late. Which is rare. I usually get AF every 28-29 days. I took a test 1 day late and the “line” was soo faint you’d think I was crazy. Well it’s now 3 days late and I’m scared to test. I am having dull cramps from front to back and like a heaviness in my pelvis that makes me feel like I need to 💩🚽. Idk if I should test or if I just ovulated super late. Side note: about 5 days ago I had EWCM AGAIN and some twinges and pulls. I was thinking maybe I’m just now ovulating but then I took an ovulation test and it was negative. 🤷🏽‍♀️🤷🏽‍♀️. Maybe I should wait until period is missed all the way? Just in case I ovulated late… any advice ladies ????
