Plan B… or pregnant

So about the first day or two into my fertile window I had protected sex but the condom broke. I took a plan b as a precaution. I’ve taken a few plan b in my life so I know typically how my body reacts. I started bleeding about 5/6 days later like barley any blood but I noticed when I wiped. So, fast forward to now. My period is almost 5 days late. I know plan b can impact your period and can cause spotting before your period is due and it can cause a later period. I’m just not sure if I should take a test or give it a few more days/weeks. I have no outstanding symptoms. I have noticed I’ve been eating more/hungry more and I have been urinating more than usually. I have had a few random days of dizziness/nausea. At night I have these almost period like pains but then I don’t get my period. I have been getting tired sooner than usual and sleeping more than normal. I don’t have tender breasts. Any thoughts. I know taking a test wouldn’t hurt but I don’t want to really waste money if it’s most likely just a late period due to the plan b.
