tri-sprintec and spotting

I switched from yaz to tri-sprintec this past month and I started spotting about a 8 or 9 days into it and havent stopped. Some days its just a little spot and other days it bleeds like my period. I have been doing this for 14 days now. If anyone knows what this is or has any thought it would be greatly appreciated. Im pretty sure Im not pregnant because if I have sex with my boyfriend he wears a condom and still pulls out even when Im on birth control. Thanks

i am doing the same thing, though i just had a baby on oct 2, 2008 and at my 6 week checkup my doctor gave me tri-sprintec. He had me start it that day which was a monday then three days later a began to bleed. It lasted for about 3 weeks. Yesterday i started the white pills and still; no period. So was that my period i had to begin with. I'm so confussed because i did just have a baby so maybe it was my period. But then will i still get my period this week since i am on the white pills?
