I'm beginning fertility treatment with chlomid and AI and it looks like I will be on vacation during my most fertile time. Should I cancel our vacation? Can the doctor "bring on ovulation" early even when I naturally would not have it? Also, my friend told me she went though one round---it failed--and then a few days later she tried again (the doctor, she said, brought ovulation on in the same month) Is this really possible? Thank you.
