Hi Faythe. I for one can sympathize with Katie all the way. My last cycle was 72 days and I DIDN'T take any supplements like soy or AC or anything. My body just never got itself worked out. And I had been off birth control for about 4 months. At CD60 I decided enough was enough and made an appointment with a doctor. I am 28 years old, so I have a little bit more time than Katie, but am not blessed with nearly 20 more years of fertility either. Anyway, my doctor's point of view was, it doesn't matter how long you've been off birth control, if your body's "broke" then fix it. There's no sense in waiting it out and hoping that your period will eventually show up or not. The cycle lengths prior to the 72-day one were 39, 55, and 45 days each. When I finally saw my doctor, he also told me that he doubted I would have started my next cycle on my own for a while anyway, because it was clear to him that I was not ovulating. He prescribed Provera to get the ball rolling, my period started, and 2 weeks later I actually ovulated. Which for me is extremely early compared to my previous 3 cycles. I truly believe that Provera is responsible for that.
Anyway, sorry for rambling, but, I don't believe that Katie's vitamins are the sole or even the main reason for her long cycle. (I am one of those who tends to believe that soy and agnus castus is probably just a bunch of hokey anyway.) But I think it just happens sometimes when you come off the pill, and she's been off of it for nearly 5 months now, that's plenty of time for the body to sort itself out a little better than it has. If she wants to seek medical assistance then I fully support her because I've been through it myself.
I know you're trying to help, and with the best intentions. We all are. I also would agree that maybe stop taking soy and AC because it's not likely THAT helpful (just my opinion, and not based on any science.) But I think you just have to really understand where she's coming from.
We're all just so desperate for the
