Hi guys so im having a mixture of feelings. I have a 21 month old son and had a hell of a delivery with him (forceps yoooowch!) So i decided to have the marina copper coil put in as contraceptive DP of 5 years and i have never used condoms (im allergic to the lubricant on them and wasnt a big deal for us as i was always on an alternative. So anyway, ive been feeling pregnant and quite unwell for a while so went to the dr for blood test and got a letter that i needed to make an appointment so went yesterday to be told im expecting!! 
Were happy and excited but really confused as i have the coil the dr checked and its still there correctly and ive had my usual period every month with no change.
Anyone else had this?
