Hey Nikki
Thought id add my two cents. I had an HSG at the beginning of all my FT to check my tubes, im pretty sure your gp could refer you for one and it is done at an x ray place. You are generally given some form of pain relief and antispasmotic before you have it done, i had an ibuprofen type pessarie about half an hour before. I wouldnt say it painful, but it is uncomfortable and you can watch them on the xray screen as they insert the dye. In answer to your question i do think it may ahve gone in the wrong place as you are right if it doesnt go through the tubes it would stay in your uterus and slowly leak out when you go to the loo etc. not just go into the abdominal cavity. definately sounds abit suss.
sorry nikki i just read that you went to your GP dont know how i missed that bit (blonde moment) i will leave this info on here though as it may help
i wouldnt worry too much (yes easier said than done) but if hes put it in the wrong place to begin with then the test would be totally inaccurate. also like smithy i only have one tube left and had IVF and am happy to say im 32 weeks pregnant so it can still happen tubes or no tubes. Good luck and i hope you get some answers soon.
