BLUE TONGUE SKINKS

I have a pair of IJ's that mated several times back in December and November.I had been hoping she was gravid ,but due to her still allowing him to mate her i decided most likley not.I had not had them out together in some time,but the last week or so when my male attempts a lock,the female bites him.She is also huffy with me when i pet or get her out.Does this mean she might be gravid?I was told that she wont allow him to mate if sje was gravid .

You can't really tell anything from that. She might be gravid, but it would not be unusual for her to act like that whether she is or not. Females will generally only allow a male to mate with them during their brief mating window that in most cases only lasts for a couple weeks.
