Latest CD for injectables?

Lacey

Hi everyone! AF reared her ugly head and unfortunately my RE office is closed. I'm sure they'll have me come in on Monday for baseline u/s, but at that point I'll be on CD 4. Is that too late? Last month they started me on CD3 and I got the impression they dont like to start later than that. I'm on Follistim. Last month was 150mg but I only had one good follicle so RE said he would up it the next cycle. This will be IUI #2. Thanks!
