Left shoulder pain, 3-4 weeks pregnant, q ectopic?

Claire • 2 MCs in 2014, hoping for a sticky bean third time around, due Nov 2015 🙏
Really worked myself up into a panic and desperately after some advice. 
Found out I was pregnant this week and am only 3-4 weeks but suddenly got pain last night in my left shoulderblade and it's on and off today when I move. Rightly (or stupidly) googled the symptom and it said ectopic pregnancy....have no other symptoms of it really but do you think I should go get checked or would it be too early? Haven't even made a GP appt yet to confirm the pregnancy. Am really scared as had mmc in April and don't want this to be another loss :(
