our clinic provided alcohol wipe and i'd be reluctant to NOT use them - proper aseptic technique will reduce the risk of infection at injection site, particularly if you do nick a blood vessel. you have to think - you might not have had a shower since morning, been sweaty during the day, no idea what bacteria are living on the site... plus i usually use the wipe to apply pressure again after the injection to stop bruising... if the clinic don't supply wipes, you can pick them up pretty cheap at the chemist...

our clinic said to swap and change the area where we jab so as not to get bruising in one area (if you're susceptible to bruising!) so i started off doing a bit of a path across my lower tum. last time round, i was experimenting myself to see what would happen if i did all jabs on one side - i have no bruising at all (well, the very last booster shot bruised) but i ended up with all my response being on the one ovary, and it's now significantly swollen (about 40 times the size of the other one!) so mix it up to get an even response.

FWIW - i did every injection myself except for the couple that the nurse gave me no choice - she had me in a rather compromising posi following u/s so i couldn't fight her! i found i was able to reduce discomfort because i could control the flow of drugs - particularly trigger and booster shots - to minimise the impact. inject a bit, rest to let it settle, inject again. i didn't have that control when the nurse did the jabs, and they tended to hurt more. i wouldn't let DH do it cos he was too nervous! plus for me, half the time i was home alone and had no choice...
