Switching pills need advice

Hi! I have recently switched my pill from tri sprintec to tri previfem. I finished my pack of tri sprintec on the 4th day of my last period. And I started the placebos in my pack of tri previfem on my 5th day of my period. And I’ve been having unprotected sex ( he’s been pulling out )

I just wanna know have I still been Protected this whole time ?! Because I’ve been feeling a little weird lately
