Good day! I hope to someone can answer my concern, please. First day of my last period was on Dec. 19, 2016. I had sex Jan. 1, 2017. Few hours later, I took Glanique 1 (levonorgestrel 1.5mg) I am not sure if my calculation is right. But was I fertile/ovulating on the day I had sex? What are the chances of me getting pregnant. Thank you in advance.
