could it be falling into place

So when I started the whole clinical trial thing  month ago. I met Rebeka who works at a research center in Clearwater (about 2 hours away from me) She said they had a trial for IVF that cost 5,000 for everything!! Well I had NO money at the time and had to turn it down. I told her to call me if anything comes up she was SOOOOO WONDERFUL ABOUT IT!! ANyways on Fri. I decided to call and check up and see if they had anything! She told me they had 2 slots left in the same trial!! Well at the end of the month I will  receive 3,000 stipend for my certification work. Also, teachers receive their summer pay at the end of JUNE. Its like 4 checks at one time. The problem is should I take 2,000 from my summer pay to put with the 3,000 I will get and do the IVF?? I am working over the summer and I could replace the money but in August it will get really tight, but we could make it. I am so nervous!! I want to take a loan for a least 1,000 for a cushion. I don't know...What??? I am nervous that this might be the chance we are looking for..but what if it doesn't work?? I don't know....
