I don't see the 'registrar hold' status in the WHOIS info, but if your name is Jennifer and that's your email address under the administrative info, then you're in control of the domain name.
If you can't login to change your info, you could transfer it to another registrar (as long as that's your email address) and just follow the instructions they email you for authorizing the transfer.
Godaddy.com, as an example, is currently doing $6.95 transfers, which adds a year to your current registration period. If you filled out their transfer, you would get emails asking you to authorize the transfer, to verify that you're really the owner. Once it's transferred, you would just login in through their site and have full control over your domain, no matter where your site is hosted.
Of course, none of this would apply if that's not your email address in the administrative contact info.
Hope that helps!
