English Bulldog Spayed?

I adopted an English Bulldog back in December. I was told she was spayed at the time. I was also told she was house broken/potty trained and that she was not aggressive. I found out quickly that she wasn't, in fact, house trained/potty trained and she does get aggressive. She does have some scars on her belly, but with this breed, if they are pregnant, they deliver the puppies via C-Section which can also lead to scarring. Here we are 6 months later and she is trying to hump my male. She tried to hump him and he moves away from her but then she sniffs his private and tries humping again. Is this her trying to show dominance over my male, or could I have possibly been lied to about the spaying? Maybe it was for their piece of mind to make sure I wasn't taking her with the intentions of breeding? I have not seen any blood but she has been outside and refusing to come in for more than a few minutes. I know the only way to know for sure is to get her into the vet but we live in a small town and getting her into the vet can take a few weeks. And before some of you get nasty, YES my male IS FIXED.
