Hi it has been a month and a week since that fake period after taking plan b. That period is very similar to my period it's like it's my period already. I am now a week late this month I still have no period. I feel too much back pain for a week now, I notice brown spots in my underwear almost everyday. Is ths normal? Should I be worried? By the way I had protected sex with condom which did not broke and took plan b less than 12 hrs afterwards. Pls reply :(
