Is It Safe To Take Next Pack Of Pill Or Stop For Periods To Start?

hi, i went to take my pill on monday and i saw that sundays was still in there, so i took both as i thought i had missed a pill. However just yesterday i saw that the 1st sunday of the packet was missing, which it shouldnt have been as after my break i always start back on a Monday. Therefore I hadn't missed the pill, just mixed my days. Now do i carry on to the next pack or take a break after this pack, as i only had 5 tablets left after taking the 2 on Monday?
