birth control
"I was using Tri-Previfem for 2 1/2 years (absolutely loved), but last June when we moved my new pharmacy changed my brand to Tri-Sprintec. Low and behold, four months into the new pill, I got pregnant. My youngest is 6 and my oldest is 10. Never had an issue with birth control before. I'm very upset with this brand and I don't recommend it."
