abnormal uterine bleeding
"I went to my OBGYN for my yearly appointment and she refilled the same pill that I've been on for two years. Loved Trinessa, did its job, I could estimate the time of my period down to the hour. Lasted 4 days. And for being a person that switched pills for a year trying to lessen my sad feelings, Trinessa really did me well. 

So, after my yearly appointment, I went to pick up my new, yearly prescription. CVS stopped carrying Trinessa and gave me Tri-Estarylla instead. All they told me was that they did not carry Trinessa and that this was the same chemical compound, just a different generic brand. Well now, I've been on this new pill for two weeks, and I have yet to stop bleeding from my last week on Trinessa! Spotting is terrible."
