Anyone trying Letrozole? I had 2 rounds of clomid at the start of the year but it caused blurred vision. other than that and a chemical pregnancy no symptoms of anything. Had a bit of a break. I'm now on day 4 of letrozole I've had headaches, nausea, hot flushes, mood swings you name it. Anyone else had worse symptoms with letrozole than clomid? Anyway thought maybe if there's a couple of us we could support each other through the cycle? X
