My friend had progesterone injections in the bum for about 4 - 6 weeks after her transfer.
I was NOT looking forward to that but fortunately, they've given me Cyclogest, vaginal pessaries, 1 in the morning and 1 at night.
The night one is fine because I insert it right before I go to bed, and now that it's been weekend, I do the morning one and then relax in bed with my book and a cup of tea.
It's quite disgusting because it leaks (sorry if that is TMI but this is an infertility blog, right?!) but I'd rather have this than an injection every day.
What kind of progesterone are you getting?
