Urgent please help!

Okay so I forgot my pill last week and stupidly, I decided to have sex a couple days later. I began to have pains in my lower stomach, like cramps. I had sex again today and I bleed a little bit after. Should I go see a doctor about it now or wait and see if it happens again? Could I be pregnant? I get my period next week so could it just be coming early as I missed the pill last week?
