Dull one-sided cramping - early etopic sign!??

Tina

I don’t have sharp or debilitating pain but every now and then a handful of times a day I have dull pain in left side sometimes where my leg means my torso on underwear line and other times in line w the top of my pelvis in closer to my belly button but below it a couple inches. Any reason to think this may be start of etopic pain at 5w2d or just growing pains? No fever, nausea or bleeding...
