Right so this is going to sound really strange but ima just say it how it is

I've had 3 MC , I'm currently late, 6 days! I have two tests here but I'm really not wanting to test, I took a test 2 days before AF was due and was neg I am normally awash regular, last period was weird asf literally lightly bleed for half the month.. The period before that was weird too.. Spotted for a few days, stopped had pinkish pee when i wiped then spotted a few days,
Well me and my SO BD yesterday & I had such cramps and shotting pains in my nunnee, well I'm sitting here now and my nunnee hurts like an uncomftable.. Kinder shotting dull pain like it's hard to explain it feels like it's right on my hole ( sorry to be so crude ) but obviously I know it's more muscle pain or something... Like what is going on? 
Shall I test tonight Or wait for my first pee in the morning??? 
I'm just really dreading it if it's BFN, I know how down its going to make me!
