Bleeding after IM progesterone injection?

Nicole • hi all! Mom of 2. 2019&2022

So I’ve been on the injections since March 19 and twice so far I’ve bled a decent amount after removing the needle after the injection, I always do the check where you pull back a little bit after You insert it but I never see blood in the syringe. Usually after 98% of the injections I have maybe a drop of blood after. Has this happened to anyone else?
