infected tooth! 😬

I have a permanent baby tooth I found out was decayed during my cleaning at 5 months preg. It would require extraction and the root was so small, there was such a little chance of abscess. I was hoping it could last until I gave birth. However I'm 31 weeks and the gum around it is now infected. I know it's needing to be pulled asap.
 My question is should I be on antibiotics before they pull it? I don't want the bacteria rushing into my bloodstream when they are removing the tooth and cleaning the gum area.
