Megsmum -sorry, posted at same time. You would normally start injectables (I use puregon) on Cd2-3
but that could potentially be stretched depending on your natural hormone levels. I don't ovulate without meds so doesn't really make a huge difference when i start but if you do cycle on your own then it would need to be CD2-3. Be aware, weird stuff can still happen on injectables. I've had 6 cycles of puregon with everyone quite different. One mth things will go like clockwork and I'll be triggering on CD8-9 and then anther it will stretch out to CD 14-16. Hope you don't actually need to do another cycle.
