"I like this pill because:

1. It doesn't cause migraines with aura, which the combined pill caused for me. 
2. I just got my first period after five months of taking it. This is wonderful for me because my periods are excruciating. 

However, there are some slight complaints. 

1. I don't like the frequent spotting. I take my pill extremely regularly, and the spotting seems unrelated to how well I take it, which is annoying. 
2. I hate how painfully sensitive my nipples have been. On a bad day, something just moving across my nipple feels like yanking!"
