I had first time penis insertion but when it started hurting, my boyfriend pulled out. He was not entirely inside. I was ovulating at that day and he was not wearing protection but he did not ejaculate as well and he was inside for few seconds only. However, for precaution, I took ipill within 15hours. This happened 2 days a go and I am really worried. What are the chances on me being pregnant? Very low, low, medium, or very high?
