my sister in law was ttc for 3yrs in the last yr she took clomid and her hormones were quite crazy it got that bad she did not talk to me for 6months.basically she got a bit depressed about not getting pregnant etc.
which is understandable.it did make her ovulate but the funny thing was after 8 months she stopped taking it and a few months later found she was pregnant.Perhaps the clomid kick started her body to do the right thing or she had enough of trying and it just happened.The body does mysterios things.good luck and i will ring me SIL and find more info
