ok i did a stud service and im not sure if my female got bred but she does have marks like where the male bite her all the way up the body, Does this mean she was bred?
it doesnt mean she is bred or gravid. the only way you will know for sure is if you a) saw them actually mating (and even if you saw them mating she still may not be gravid ... it helps to know if she was ovulating or not) or b) when she produces eggs
sometimes the male will stimulate her into ovulating but just because she has bites doesnt mean she had been mated with or is gravid
