Females generally dont have any redness when popped. Its possible that you may have injured her especially if she has an indent right in the area where you where pressing. I would leave her alone and not try popping her again anytime soon. If she eating and behaving normally and not bleeding out of the vent or something like that I would think she will be fine but I just leave her be and try not to compound any injury that may or may not have occured. Sounds like she will be fine though.
