I had unprotected sex with my boyfriend on the 13th and took the i pill the same day after 3-4 hours, I had a light period for about 2-3 days after a week of having iPill, now it's been a month and I haven't had my periods yet, Can I be pregnant? I took a pregnancy test but it said negative. My breasts and nipples are sore and I don't know what to do. Please please help. Is it normal to miss a period after an ipill, or are my symptoms that of a pregnancy. I cannot tell. Please answer.
