Bleeding while on the pill? Period or pregnant?

I’ve been taking the pill for 2 years now. No problems. No spotting. Always on time periods. Never late. Never early. I have missed 2 pills this week but taken them the next morning (so I doubled up some days) but today at work I got my ‘period’. My period isn’t due for another week and I’m still taking the normal pills. My boyfriend and I have had unprotected sex twice within the last week or so. I’m so confused. Do I wait a few days and take a test or just let this ‘period’ come early and forget about taking the rest of my packet.
