i want my wedding pictures back soooooooo bad....or at least a picture.

So it's been about twelve weeks and we haven't gotten one picture from our wedding photographer. This would be fine considering our contract says we will get back photos 18 weeks or less (if I were to go back in time I probably would have picked someone with a shorter turn around time, but at the time we just didn't think about it); however, she gave back other couple's pictures within a few weeks of their wedding, one of which was after our wedding. Granted, these may just be sneak peaks, but why would other people get pictures back so soon, but we wouldn't? It makes me worry that she either didn't like us, or she doesn't like our shots as much as the other couple's. I really didn't want to bother her, but I think my husband got tired of me talking about it so he decided to message her and ask when we could expect to get our photos back. She said we will get a sneak peek very soon and she will get us our pictures in about a month and half. She told my husband that she's working on a wedding from before ours, and once she is done she will have room to export our pictures into her computer. This would all be well and good except I know for a fact she's already edited pictures for a wedding that was after ours! I just don't get why she would upload theirs within less than a month, but not upload ours until now. Are there any photographers out there who can give me some sort of an explanation!? It is hard enough to wait, but watching other people get their pictures back sooner just really makes it ten times worse.
