AF during IVF. HELP Please!!

MissJelly
Hi. I'm doing IVF and at the moment am on the syranel nose spray. I'll be going to the IVF nurse on Tues with the plan of starting the FSH injections on Wed. The plan is that we'll have egg collection in the week of the 7th and egg transfer 3 days later. 
​My period was due today or yesterday and if came today. Not just spotting the real deal. The nose spray is also used to manage endo. The brochure said you can getting spotting or AF while on it.  I'm just wondering if anyone else had this and if it stopped you being able to progress with the rest of the IVF cycle. I'll ask the nurse on Tues, but I don't want to wait any longer and am a little worried we'll have to wait until the next cycle in Sept. Any advice would be great. Thanks in advance.
