Injection

So I've been taking injections since 2021 first plegridy now Kesimpta No bleeding First blood today 😂 this time I've injected myself and drew blood 😅 I don't feel like I did anything different, top of the thigh. Though this is the first time I've been given the cotton swabs and wipes along with the medication for the injections so maybe it was an omen So my question is do many of you often draw blood when injecting? 3 years, so maybe it was inevitable 😂
