I had a HyCosy on the nhs. I was told it had to be done as close to day 14 of my cycle as possible (so I had to book it at the start of the month) and not to try for that month, but I could start trying again after the HyCosy had been done. So because it was day 14 it was a very slim chance that it would happen that month. I had one lot of antibiotics while i was in the treatment room but that was all. The doctor said that statistically people have a higher chance of falling pregnant in the 3 months after having a HyCosy...not for me unfortunately as I’m still not pregnant over a year after having it done! He also told me some people barely notice any pain, whereas some people find it very uncomfortable and painful. For me, the actual procedure was a bit uncomfortable but it was tolerable. However, on the way home (they recommend that someone comes with you to drive you home and not to take public transport), I was in a lot of pain. It felt like the worst period pains of my life. I felt like it must be what early labour pains felt like! Sorry, I don’t want to scare you, but just want to give you a heads up as I wasn’t expecting that. The paracetamol didn’t touch the pain. Once I got home and got comfy, it soon went away though. However, saying that, if I had to have it done again, I would....so although it was painful for me, it wasn’t so bad that I couldn’t face doing it again if you know what I mean! Xx
