Pristiq & intrusive thoughts

I’m on Prozac and Buspirone for my anxiety/depression and have been for 12 years - I’m now 28. My intrusive thoughts, low libido and depression gets worse the week before my cycle and week of, and I started sweating at night. I tried all the things - new fan, higher fan, new sheets, new pajamas…still sweat so I started tracking and the days line up month to month. I brought it up to my gyno and they said I’m too young for hot flashes or anything serious that would cause this. I brought it up to my psych and they want to try adding Pristiq.

Does anyone have experience with Pristiq or can shed any light on the night sweats/intrusive thoughts? I feel miserable and just sad during those 2 weeks and I’m tired of it!!
