I was taking phen when I found out I was prego. I think that maybe your reduction in calories has a lot to do with irregular periods.Im no doctor though.When your body goes in to starvation mode even when your not feeling it (thank you phentermine) alot of things go wacko, especially your monthly cycle. Although I immedietly stopped taking phentermine with my pegnancy I got really scared when I was told that my daughter could be born with heart problems(never proved to be the result of taking phen)Anyway after all was said and done She is now two years old and healthy as a horse, I on the other hand remain fat as a cow. My doctor refuses to prescribe phentermine blahh blahh blahh. Ive looked around to find a doctor that is willing to write me a script and they say that it is "not a drug that they are willing to prescribe"Well all I know is that It WORKS. I went from 170 to 128 and kept it off til I got preg. Good luck to you
