Again, I'm no expert, but this is my understanding.

1. Clomid can help some women ovulate. It does not work in all women and the dosage required may have to be increased for each cycle that it doesn't work on. Some women will never have success with it. I never conceived on it, although I did O.

2. You can still O after going off it. I conceived 3 months after stopping taking it 10 years ago. I had an early m/c.

4. I don't think it does anything differently to how your body does it, it just gives you a helping hand if you require it.

5. Clomid can help sustain an early pregnancy and some FS use it that way for women who have had a m/c or two even though they are ovulating.

6. It does increase your chances of twins and triplets so if you are only looking at having 1 baby I wouldn't suggest you use it. As you get older (35 onwards) the chances of multiple pregnancy is also higher (as more eggs are likely to be released as you head towards menopause) and adding clomid to the mix puts the risk even higher.
