HSG test-who's had one?

Libby
Im booked in to have a HSG test and I'm not so sure what to expect. I've done some reading online and I'm fine with the discomfort it may cause. I'm more excited to see if my chances of conceiving are increased after it. What's your experiences with this test? (Am not just getting test to boost chances of conception. I haven't had a cycle in 5 months so this is just checking if I have any blockages)
