Hi everyone! I was wondering what is the latest CD possible to start injectables. AF reared her ugly head today and I won't be able to get into RE office until Monday for u/s (closed for the weekend except for certain procedures. Monday will be CD 4. Will this be too late? Only my 2nd <a href="https://glowing.com/glow-fertility-program">IUI</a> attempt so I am still learning and nervous. On Follistim and HCG trigger. Any information is welcome! I also posted this is another group so I apologize for those of you subjected to this 2x, just trying to get as much feedback as possible. Thanks!
