Hi, I had unprotected sex on November 8th around 1:00AM and I got plan B the next morning and took it around 10am. I am worried because the night I had sex was the first day I was fertile in my cycle. After i took plan b, about two weeks later I have been noticing a thick, light brown discharge. It started on the November 19th and it has been happening since (20th). The discharge is sometimes an excessive amount of it, and sometimes it is not. Also, I ve notice my boobs have been sore lately, and its unusual because that only usually happens a week before my period. Although, my period is not expected until the 27th. Should I be worried?
