I conceived DS after 3 cycles of Clomid. From what I can remember I think Clomid should make you have a noticeable visit from AF. On my first round my cycle was tracked via regular blood tests so there should be a way your FS can answer your questions by looking at your blood work. But just in case a BFP is on the way check with your doc before your next cycle. All the best it sounds like this could be it for you, I send heaps of your way .
