Turns out I am pregnant doctor says I'm 3w5d tomorrow I'll be one month pregnant, thank you all.

It sounds like you're really trying to get pregnant, and yes, you could be.
I'm not sure what "back legs and arms cramping" means, but those aren't symptoms of early pregnancy.
You could always take a pregnancy test tomorrow, if you want. Maybe it will show up positive, but likely not.
Only a hpt or a blood test for your hcg can tell for sure, but you definitely could be. It is still a little early for a long of the early pregnancy symptoms though.
