Hi Lime. Yes, this definitely could be the meds, specifically the heightened anxiety. Anxiety in particular can throw your cycle off so it’s certainly possible that this is what is happening. I have read of this happening elsewhere as well.
I had a panic attack yesterday and today I have been feeling a bit off. Blah. This is fifth week and I have been on 20mg for a week now. I have heard that the clock starts when you start taking a therapeutic dose and not a sub therapeutic dose which means I have a long way to go before any substantial improvement : /
