I tried Fenugreek 1 x 3 for about two weeks back in January and I had awful side effects. Chest pain, constant spotting, my stomach hurt, and I was getting crazy headaches.
My hormones were all messed up already though from my IUD and I started fenugreek again when I was put on the pill to regulate my cycle. Partially because I wanted to see if anything would happen and also because I am cheap to the core and hated that I'd paid for pills I wasn't using
This time around, I took 2 x 3 for about 10 days and my skin broke out horribly. I stopped taking them because my skin was bothering me. I did have a bit of swelling in my breasts, but mostly my skin was bad and I was really tired.
My skin is always awful though so maybe you'll have better luck
