Eptopic pregnancy

Ok dont know if ive spelt that right (sorry) but what are the symptoms? I had an IUD put in 5weeks or so ago. And i have very intense pain in the center of my stomach (but its not stomach pain). It feels like someone has punched me and it hurts worse when i walk or bend over. Doesn't hurt too bad if i am lying down. I have had this since last night. But it hasnt been too bad today although i havent done much, just flared up when i took the kids out for a walk. If there are any other ideas as to what it would be that would be appreciated too.
Pretty much just want to know if i need to be seeing a dr asap (if its like an eptopic) or if im sweet to just see if it goes away.

Thanks

Hmm Can you ring healthline from a cellphone? We dont have a landline

My ectopic was intense pain just a teeny bit off centre. It was on and off but when it was there it was awful. Doc thought I was just having a normal miscarriage (idiot). But I'm not allowed to have IUD's because they do increase the chances of ectopic pregnancies.

Well i rung healthline and the nurse said unless the pain is completely constant and unberable not to worry about it. I guess il try get an early night and if its still bad in the morning il book to see the dr. Of course if it gets worse i will go to a & e. She didn't think it was related to the iud.

Thanks for the help ladies.
