And under the receive tab, since my transaction is still pending, will I loose all my money in 23 hours when the request expires?
requests don't expire btw. that part of the interface needs some rewording. suffice it to the address you got from the receive tab will continue to work forever and you should have no problems receiving money to it now and in future.
as for the confirmations issue don't worry either the two transactions will confirm or they won't. you won't lose money. just wait it out.
