Overthinking symptoms!?

Jade

AF is due in 2 days. Ive been testing the past few days and been getting negatives, but i have a few symptoms that i never have before AF. I've been having cramping/sharp abdo pains, boobs are sore, waves of nausea! I'm currently 12dpo and with previous pregnancies I've tested positive by now. I guess my question is, has anyone had late positive pregnancy tests!?
