Cramping is very normal, only time will tell just make sure you have a ultrasound before 11 weeks to make sure everything is fine. Example like no atopic pregnancy where the egg implants in the fallopian tube
Sharp pain on the right side isnt good espec if u see that ur spotting aswell. If the sharp pain gets worse do go to the hospital to get checked out as it could be a sign of ectopic pregnancy. I'm sure its nothing but its better to be safe than sorry.
