Oh this is so hard, but it will pass. Hang in there.
I would'nt go that "tough love" route. They won't learn to hate it, they will learn to live with it and set up a pattern for wallowing in it for life.
Did she "go" at 7:30 when you took her out? If yes, good. If no, then put her back in crate for only say 15 min. and try again. When she does go out side...praise, praise, praise. Make it a party! Also, it's useful to start ueing a command...as soon as she starts to "go" say something like "pee-pee, good girl!". Eventually this will be something she will do on command. If she has an accident inside....ignore it and calmly clean it up. Remember, even a negative reaction is a form of attention and can reinforce a behavior. Praise what you want to keep, ignore what you want to go away. Takes time, but works.
Back to the problem at hand, did she eat after her 7:30 outing? If yes, this likely triggered the need to go. Puppies are food in, pee/poop out. So, I'd take her out within say 5-10 min. of eating/drinking. Also, we have one dog that doesn't always "do it" all - only enough so it doesn't hurt any more

first thing in the AM...guess he's in too much of a hurry to get his breakfast.
Like Pumba said, make sure to clean/ disinfect the crate each time she has an accident. You'll need an odor neutralizer to really get rid of it. Try something like Nature's Miracle or our fave is called Urine Kleen...it's made here in Maine and available online through GG Bean...if you can't find it let me know...I'll track them down for ya.
Good luck! Puppies are so precious. I should know....we have 6 at the moment. You think you have pee problems!
