Birth control

Hi guys,so just today I got switched from ortho tri cyclen to the generic version of that (tri-sprintec) I had taken this bc before and hated it the first two weeks because it made me feel so sick. However,is it safe to still have sex without a condom when switching between brands? I'm on my period right now because I just finished the sugar pills on the ortho tri so today I'm gonna start with the generic ones...
