Clomid- question

I have a question, so when I got it I was on cycle day 10 and I talked with my sister and she told me to just take it (that's what she did and got two sets of twins...) she told me not to worry about it as long as I did not ovulate. I did not so I took it cycle day 11-15.... I feel so guilty. I just want a baby so badly. Has anyone else do this? HELP!!!!
Feel guilty because I took it on the wrong days
