Hi, I had unprotected sex on 3/10/2016, and I saw my period on 12/10/2016 for 5 days. But right now, i have very tender and swollen breasts and nipples. I had unprotected sex on the 19/10/2016, but I took the morning after pill after 10hours. I m just abit worried if this is a side effect of the pill, or a pregnancy. PS: this just started 2 days ago
