Late period but on birth control , help

Hi, not new to birth control as ive taken it on and off for a while now. I'm taking Lo Loestrin Fe, i skipped the placebo pills the first month bc my period came right before and i didn't want to have 2 yknow? This month i took them all as normal. Period was expected 2 days before the placebo pills start, I've got one pill left and my period is now 6 days late. Probably should mention I took a pill pretty late one day and didnt have sex on that day. Sexually active but we use condoms or he pulls out wayy before hes close. Just need advice on if im expecting my period still. Or when/if i should take a pregnancy test. TIA
