This pill leveled out my mood so I didn't get as much pms. I took back to back for 3-6 months at a time, after about 6 months I would start to feel stressed/anxious and would need a break. On my break I would bleed heavily for several days on day 4, even though I started the pill again I still had the desire to have sex, though it wasn't as intense and it did not vary across the month. My main issue was vaginal dryness which was so bad that lube didn't help and sex became painful particularly when I was stressed. The effect increased over the course of being on the pill and was not consistent, but went away once I stopped it
