Possibly not! Are there any other symptoms you have? Just cramping is not a POSITIVE sign of pregnancy, but it can be one!
2 weeks after i concieved i had flutters in my stomach and felt faint and tired alot. I also had a severe cramping before that, especially when i sat up! (I read the cramping can be the egg attaching to the uterine wall which would occur about 10 days later i suppose?) I thought i may have been experiencing low BP, but i also had a weird feeling about it all, like i suspected pregnancy. A couple of days later, my breats were sore and swollen, and starting to show blue veins. It ended up i was pregnant and gave birth to a beautiful baby girl on the 14th August.
The only true way to tell is to go to the doctor or take a test. I took my home test the day my period was due and it was positive.
I hope everything works out for you! They say there is a Mother's intuition, the Doc told me if you really think you are pregnant (Not just wanting it) you are usually right!
too early for symptoms? 
Just be patient and wait for the test time. If you would like to be pregnant, and it turns out you are not, there are many more months
