I think there is so much inconsistencies with how FS treat. I've had 3 cycles on clomid and saw my FS just before Easter. I asked him if I should be having US during my cycle and he said it wasn't necessary (but so many other women on here have them, so I don't know). He said my BBT indicated I have been O'ing, so just keep DTD and come back in June/July. If he wasn't the head of a reputable FS clinic I may be more worried. Perhaps I am being naive.
It certainly is a rollercoaster ride! Good luck and fingers crossed your stay here is short
