Cramping before BFP?

Ja

This month I have been really good about not symptom spotting however I’ve had mild, dull cramps intermittently the last 3 days. Last night I woke up multiple times with cramping, nausea, and heartburn thinking it was AF but nothing. This morning I’m still having dull cramps. I don’t get AF cramps until I actually start and they are usually very intense whereas these are more annoying and mild. I will get a test this afternoon but I’m just curious if anyone has had cramping before their BFP? AF is due today...
