no more pill

We decided to ttc. I made the mistake and stopped taking the combo pill mid month. Later i found out i need to finish the month of pills. My period started 1 week early. It normally lasts 4 days max. I have been bleeding for 9 days. I am still spotting. Is this normal? App says I will be fertile in 2 days. Is that right? This is all new to me. Thanks
