advice or insight ladies?

💋A Babin🌸 • Conspiracy theorist 🤷🏻‍♀️ married to the man of my dreams💍 two kids, one in the oven due may2018
So the hubs and I have been "not careful" for almost two years and welcome a pregnancy, and as of the last 6 months have decided to chart everything and actually try and aim to conceive purposely. June we managed the day before ovulation and the next two days after. Ovulation was about the 17th--- about a week later I had some light cramping (about 24/25th).. my period was due yesterday, the 30th... I haven't started, and I'm not cramping or even bloated feeling at this point. I took a test yesterday and it was negative. 
1)Would you say the light cramping was possibly implantation? 
2)And about how many DPO do you ladies averagely spring a positive?? 
I don't want to buy a bunch of tests to test every morning, and before anyone asks, this was the first month in 6 months I wasn't able to track my BBT. We just finished 3 weeks of moving and idk where my basal therm is.,, so I can't go off of that!
