Depending on your weight, age, egg quality, infertility diagnosis and many other factors the medication protocol for your cycle will be tailor made to you. Inevitably it will (unfortunately) involve injections... You may end up having more injections than most or you may need to do them for a longer time depending on your circumstances. Either way you will soon be feeling like a pin cushion!
I am not the best with needles and was horrified when I learnt I needed to have injections every day, however, if it helps you have a baby you will quickly learn to deal with it, because let's face it you would do absolutely anything! The first time I had an injection I was so nervous and worried it would hurt but to be honest it was nowhere near as bad as I feared. I know a lot of people get someone else to do it for them but I found it easier to do it myself as I was in more control! I had them in my stomach but I know other people take them in their bottom, that is your own preference I guess.
Each day you have an injection, generally at around the same time and this medication stimulates your follicles, in order to grow more eggs than you would usually produce. If your follicles are progressing nicely, namely of a good size and in number, then you will be ready for your trigger injection after around 2 weeks. The trigger injection is usually a larger and more painful needle and it releases the eggs for your egg collection. This is usually perfectly timed around 48 hours before your egg collection.
I am not going to lie that injections are nice, I don't think anyone on Earth enjoys them but they are a necessary part of treatment and the easier you can make them the better. My tips would be to be fully relaxed when injecting and have ice on hand. Some people end up with tremendous bruises and lumps and it does not look pretty and they can be very tender. Anything you can do to ease this is obviously a good idea! Try not to be too scared, that will make you more tense and usually harder to inject which is more likely to hurt. They really are not that bad!
