Cramping & fatigue. AF 6/8

I have been having cramping all day on and off and tonight I've started to feel very bloated and am exhausted. May was my first time TTC, I am not supposed to get AF until 6/8 and its too soon for period cramping. I normally don't get period cramps anyway. Has anyone else had similar symptoms and gotten a BFP when it was time to test? I'm getting eager which will prolly just lead to disappointment!
