My gynae has suggested I try zoladex injections so I booked up for one through my GP. Got an appointment for near the beginning of September but looked at my calendar since and realised that 28 days later (when the next injection is due ) I'm away in the west country. I'm therefore just wondering, do the injections have to be exactly 28 days apart, or is it OK to have one a bit early or slightly late? If I have to I'll move the appointment but it'll mean not starting the injections for another month and I really want to get going on them as soon as possible. Any advice much appreciated!
