So I'm going back on birth control soon and my doctor gave me refills for both Sprintec and Tri-Sprintec. I noticed there was a difference between the two because when ordering it I noticed that one says "3 phase" and the other doesn't. Which is why I called the doctors office to see which one I should get refilled & was told they were the same pill.

So Walmart ended up giving me both pill packs and the packaging is different, and I'm learning that apparently the hormones fluctuate more in one (Tri Sprintec)? I'm curious to know if anyone knows if I take one during one month and the other the next? (Like taking tri sprintec the first month then Sprintec the next) or do I just stick to only one since the hormones are dished out differently? I have multiple refills for both. Just don't wanna mess it up. I did a horrible job at explaining! I will call whenever they're open if I can, but my period is starting soon and I'm only now noticing that the packs and names are slightly different. Any help is appreciated!
