I'd find out which medications your IVF specialist prefers and then get their opinions on common side effects they see in their practice.
Every patient is different, and no one will have the same response to a medication as someone else.
The FDA requires any side effect (Adverse Event) that is present in more than 1% of the population be published as part of their Package Insert. All prescribing information about all medications is available online. The FDA also legally requires side effects be reported during and after clinical trials - which is why you hear of drugs being recalled - once they open to the general public, side effects may occur in more of the population than in clinical trials.
A pharmacist should be able to help you with what common adverse events are. I will add, though, that while I haven't done IVF, I did go through chemo and had completely bizarre side effects no one else had with some of the drugs.
So, while it's nice to have an idea of what may happen, each person is completely different and will respond differently based upon levels of medication, frequency, etc.
Good luck.
