Ectopic ??

Hi ladies !

I am currently 7w5d with my first. Yesterday I had a sharp but bearable pain in my lower right abdomen for an hour last night. It was not excruciating but was noticeable. It’s gone away since. I don’t know if it’s because I’ve been gassy and a bit constipated, or if it’s something more serious. Of course I’ve gone overboard with google and now I’m stressed that it could be a sign of an ectopic pregnancy. I’ve had no vaginal bleeding this whole pregnancy. I go in for an ultrasound tomorrow, but want to know what you ladies think. Anyone had similar pain in a healthy pregnancy?
