Clexane injections “No more bruises?”

I have a question I don’t know if it’s normal or not,

On my previous round of IVF “2nd” i started taking clexane injections and it’s known that it gives you bruises,

When i first started it i did have very dark and big bruises in the beginning but at the last few days they start disappearing and don’t get any even though i take the injection daily at the same time “then i stopped all meds due to MC”.

So i started this month my 3rd round of IVF and started taking the clexane injection on July 17th,

But i don’t have any bruises at all just a tiny little red dot from the needle,

So i just been wondering is that normal or did i become pro in injections 😅 💉🤓

By the way just to be more clear I’m asking this to make sure everything is alright and it happens to others too.
