HELP! Started period before 3 day weekend and office is closed!

So I just did my second iui cycle for my second baby (my first baby was an iui baby as well). I started my period late this afternoon and called right away to report it. However, my doctors office was closed already for the long weekend and I was only able to leave a message which said they will return on Monday. I need to start my next cycle and have always been told you need to do your baseline and start your clomid by cycle day 3, Monday will be cycle day 4. WHAT DO I DO?

Has anyone else had something like this happen? Did your doctor just get you in asap on day 4 and still let you start your meds? How did this affect the cycle for you?

This is the last cycle we can try before my husband deploys so I really really really need to get in for this cycle. Any advice is much appreciated!!! Losing my mind right now!
