?Ectopic pregnancy

Hi,

So I’m just over 5 weeks pregnant. I’ve experienced nausea , tiredness, back ache, sore boobs , dizziness and cramps. I’ve got no bleeding, however I’ve been experiencing a stabbing pain low on my right side every now and then, quite strongly. Also had slight stabbing pains in my left shoulder which I know is a sign, not too painful but it’s noticeable and it’s intermittent, worse when breathing in. Im scared maybe I’m thinking about it too much. I’ve also got pains in my neck too. Early pregnancy unit is closed over the weekend and don’t want to waste A&e time.. can anyone explain what the shoulder pains feel like in ectopic pregnancy?
