Hi. I'm under an NHS infertility clinic and iv'e to have an HSG test to check my fallopian tubes are not blocked. I'm 38 and been trying to conceive for 14 months. the clinic has already established that i'm not ovulating so i guess that would be the reason i'm not falling pregnant. How long does the HSG take to do and is it painful ? Quite nervous about it but know i need to do it if i want to take things further at the clinic. Iv'e heard that sometimes women can be more fertile after having it done ? I'm hoping that might be the case but doubtful as i'm not ovulating.
