that's about when i started feeling mine too and my dr. said that definitely by 6 weeks you'd be in some serious pain, and if you get past 8 weeks without severe pain, you're good to go.. almost all ectopic pregnancies show before 8 weeks.
Im 6 weeks! First time mommy and paranoid about everything. I get chest pain with it to which is weird
if the baby is implanted in the uterus then you're fine, when i first found out I was pregnant with my daughter i had severe cramps on one side and shoulder pain and I thought for sure it was ectopic, my dr. told me you'd have severe symptoms before getting the shoulder pain, severe cramps, bleeding, and feeling faint to the point of passing out from the bleeding, i'm sure all is well hun! :) how far along are you?
