Alright thank you for your help :)
Women's cycles can vary and so can the length of their menstrual cycles. 5 days is a normal amount of time for a period, even when you usually have a 7 day cycle. Sometimes, due to stress and other factors, your cycles can vary by a few days. It does sound like you had a menstrual cycle from the information you have given. If you are unsure, you can take a urine pregnancy test. You can also follow-up with your doctor for a blood test to confirm whether you are pregnant or not. It's not impossible for you to be pregnant, but given the information you have described, I think it would be very unlikely for you to be pregnant this cycle.
Hope this helps
