Cramping before BFP?

Amanda
I know that PMS symptoms and early pregnancy symptoms can be the same... Does that include cramping? I have had cramps on and off today, but no AF. I also have had nausea for the last week or so, only in the evenings (same nausea I got when I was pregnant before - it ended in a chemical pregnancy at 5 weeks). 
Has anyone had cramps before their BFP? I don't know if I should assume I'm out or if there's still a chance. I want baby #1 so badly!!
