She completed two IVF cycles, but only managed to freeze nine mature eggs. Usually, one IVF cycle produces about 15 eggs - and it usually takes one out of 10 eggs to produce a baby.
So, with the prospect of doing a third IVF cycle she decided to ask complete strangers to help pay for it through a GoFundMe account.
The young Queenslander says she knows she is "asking for a lot, but it's my dream to have a family of my own".
"Obviously now I can't borrow more money so I thought I'd try and raise the money myself," she told news.com.au.
"It's a lot to think about, the process, you have to inject yourself each day.
"I'm sure I'll meet somebody when the time is right and I know it's just the way that I'm born, but it's terrible.
"The clock is ticking, which is scary, people keep telling me it will all work out.
"I really hope it does, it's a bit overwhelming, but I have to hope if I can do this third cycle and get another 10 eggs, I can sit back and know I've tried my best."
Ms Kershaw is off to a slow start, however, having raised just $AU380 of her $10,000 total. Each of these cycles costs $10,000.
"It was really disappointing, I thought I wouldn't have to do it again," she said.
"I've wanted to have a least two children, so the fact I only have nine eggs is a bit worrying.
"I didn't want to have to do another cycle, mentally it's very draining, but I really don't have a choice.
"With my odds, I can't do that. They don't know why I keep getting low amounts, it's the luck of the draw. Because I have a low AMH level it makes it even worse to get those good numbers."
