Late af and high cp?

So my af is 2 days late, and my cp is still high? To the point in can't touch it, and it feels closed. Been ttc for about 4 months now with no luck... I took a test the day before af was due (5/5) and it was a bfn... Should i test again? I've been have slight cramps, and my boob's are sore, but nothing terrible. IDK i just don't want to get my hopes up just to get a bfn 😩😩
