Sami,
Re ectopic - symptoms include pains in TIPS of shoulders, very bad pain on one side of abdomen and normally brown spotting.
I think if you have any bleeding you should get to the hospital. Go to A&E and you shouldn't need a referral at all. If you go to a different hospital and they ask why you didn't go to MK just say you were nearer to them and your symptoms had worsened.
I REALLY recommend going back tonight and getting this sorted out once and for all so you know where you stand.
Thinking of you. Lucyx
