ectopic pregnancy

Kayla
Not worried but just a tiny bit nervous. I am early 5w6d I will be 6 weeks on Sunday and I have been having some neck pain... I am originally a big chested girl DDD and I'm not sure if it's because of that or what. But I've read about ectopic and I'm nervous.. I have a doctors appointment Thursday but curious if I should call sooner... :/
Please help.
I don't have any intense cramping or pain. And no unusual bleeding. Seems all normal cramps and bleeding wise... so I'm hoping it's just the weight from the girls up top..
