HI, Jodie
Not really sure about them but one of the girls whom i work with is having them done and she said they actually give the vaccinations in 3 rounds. The first 2 are weeks apart and then the next one is 6 months later i think. Not sure what that will do to the ttc. I pesonally am not going to have them right now (nearly too old for the freebies anyway) because of our ttc journey but will definately consider it in the future
Best of luck to you
