Makena shot reaction?

Nicole

I have been getting the Makena injections for the last 4 weeks and it does burn and itch and I know thats pretty normal. But yesterday it hurt a little more than normal and today injection site is really red with a few red bumps. I'm pretty sure its normal reaction but just wondered if any of you ladies had a reaction like this?

I guess that weird misshapened spot near pit is where they injected? I just haven't had this type of reaction before the last shot...(Sorry yes, need to shave... 🤭🙈)
