I have been on pills for the last two months without missing a pill. My last period was on mid-October, I had spotting two weeks ago but ignored it. Thinking if I haven't missed any pills, I should be safe. I made love on last Wednesday night (without condom). However, I had dark blood bleeding on Wednesday, which has continued till now. I am also feeling unwell since then. I continued taking the pill today thinking that it should kill any sperm, which could be there between 3-5 days. I am also having anxiety for the fear of pregnancy but I haven't missed any pill the past two months.
Should I stop taking the pill this week (I have one more week left) before the inactive pills start or stop the pills and let the periods start? Is there a possibility of pregnancy?
