I think you'd probably need to decide before starting a cycle if you plan to enroll in the study, but you could check to see if they'd let you decide to enroll once you see how many blasts you get. Usually, you can decide to test or not pretty last minute. Also - IVF takes time, so even though the study would take a few more months, you should expect it to take that long anyway if you don't test. Not sure what your #s are (i.e., how many eggs you expect to get), but if you don't expect to get many, the odds are reasonably good that you'd have to do more than 1 retrieval cycle. And if you don't test and do get plenty of blasts, chances are that a high number will be abnormal, so you could end up having to do multiple transfer cycles, which takes time.
Financially, the loss of leave should be more than $3500, so it would be better to get the leave, but as noted above, I think there's a good chance things will take more time than you're thinking and it may be that you face that anyway, making enrolling the the study a good option if you think you'll get lots of blasts.
While it sounds wrong - your chances of success are slightly better if you don't test. Some "abnormal" embryos can actually turn out to be healthy babies, but no one around here will transfer an embryo that has tested abnormal. The odds are slim that an abnormal embryo could work out, BUT it is possible. PGS testing can speed up the process and lower miscarriage chances by pointing you to the normal embryos, but data show that it results in slightly (but statistically significant) lower success rates overall.
