Tri-sprintec birth control

my doctor put me on tri-sprintec because I decided to use chantix to stop smoking. I'm on the 2nd week of this and am having a whole new period and it's awful! I keep reading that btb is common. is this considered btb?! It's been 6 years since if been on the pill because we have been ttc. decided to take a break and kick my nasty habit and now this 😣 I've also seen horrible reviews on this stuff. does anyone have any similar experiences? should I just try to switch?
