ectopic pregnancy??

Aims x
Hi,
This is my first pregnancy after a long time trying, I'm about 5 weeks but keep getting a niggling pain when I push to pee on my right side. Does hurt any other time and wouldn't say it's a bad pain. I've had a few period type cramps over the last few days. My hormone levels at the doctors seems to be where they should be but I'm terrified this could be ectopic? Any ideas? 
Xx
