Weddingbee boards

I was really sick the entire week leading up to a good friend's wedding, and therefore didn't have a chance to get her a gift before the wedding (which I barely made it to).  The following week, I went to one of the places they were registered and had one of the remaining gifts sent to their house.  I haven't received a Thank-you note, but my emails indicate it was shipped to their home address and was delivered.  It's NOT the thank-you note I'm worried about, I just want to know if there is any etiquette surrounding how I might go about trying to figure out if the gift actually made it there.  It's been just a little over two months.  She is a long-time friend from high school who I know very well, but don't want to be rude. Help!!

That's kind of what I was thinking...I'm SO not fishing for a thank-you note (honestly couldn't care less about one, actually), but I would be mortified and dissapointed if she thought I hadn't gotten them anything!
