question: Hello doctor, My period was due on the 20th of this month. I had protected sex on 14th night, and we had a bit of a doubt about the protection, so on 15th evening, I took an I-pill. On 17th night, we again had protected sex, and on the 19th morning, I took another I-pill. I did not get my periods yet. Can period get delayed? Is there a chance of pregnancy? I tested with the urine kit last night, which was negative. Is it too early for the urine test to detect pregnancy?
