Hi ladies, I just saw this thread and thought I'd pop in.
I have generalized anxiety disorder and bipolar 2. Fortunately, all of the meds that I am currently on shouldn't interfere with TTC (though I should obviously wean off of them if I get a BFP.) That said, as a side effect of the bipolar, I also get insomnia, for which my doctor had me on a low dose of Seroquel (50-100mg.) I believe that really messed up my current cycle.
I have an insanely bad history of cycles over the past two years. When I was diagnosed with bipolar, I was put on Trileptal in Oct 2014. In Jan '15, I stopped having periods, despite being on BCPs. My GP then told me that the two medications can interfere with each other and diagnosed me with PCOS, based on some blood tests and the fact that developing PCOS is a know side-effect of the drug. The Trileptal was working at the time, and I didn't want to TTC anytime soon, so I stayed on it. I got Paraguard (copper IUD) in Feb '15. Even though it was non-hormonal I still wouldn't get another period for 14 months.
I moved to Germany in July '15, and when my meds ran out in September, I had to switch to Depakote, because Trileptal isn't available in Germany. I had a TERRIBLE time on this. I was almost hospitalized, but I refused. I went off it in late November '15, and then began Lamitrogen, which has been a god send.
In April '16, I had one AF, which was totally unexpected, and it was the only one I'd have for several more months until Oct '16. In Aug '16, I was diagnosed with hypothyroidism and began medications mid-August. Oct 10th, I had AF. I had another AF 50ish days later at the end of November.
They stopped again, though and I'm one CD 81. I highly suspect the Seroquel, as it was the only thing that had changed. I began temping one month ago, and one week after I discontinued Seroquel, FF said I had ovulated (and my temps certainly look like I have.) I'm praying the medication truly was the culprit of this awful cycle.
Sorry for the book, but a bunch sort of interrelates and I wanted to give the experiences with meds. So... I'd be wary of things like Depakote, Trileptal, and Seroquel, if you can find an alternative. But that's my personal experience.
