Take 3 pills in one day

I’m so scared...I forgot to take the pill for 2 days and this morning I took it as soon as I remembered. This evening I took one pill as normal but now I’m in so much pain

My stomach is making crazy noises and it hurts so much, I don’t get my breakthrough bleeding for another 18 days

Has this happened to anyone before, and should I see a doctor or wait it out? It’s currently 11:30pm where I am

Thank you
