When can I test?

Okay so we’re trying to conceive and we had unprotected sex on Saturday and Sunday and I ovulated on Tuesday. I am now 3DPO and I was getting really bad cramping and SO MUCH discharge like everytime I wipe it’s like when you have a really bad cold and keep blowing your nose and snot comes out everytime, yeah exactly like that. And the cramps were almost unbearable. It’s now been a week since we’ve baby danced. Should I wait another week to test?
