I took Plan B on July 18 & I got my period on July 30 which is a very good sign because it's the right time for my cycle to begin . My period just ended on August 6 was pretty light and I did get very bad cramps on the first day of my period .
I am now getting lower stomach pains & back pains . Feel tired too . Are these some go the effects or is there a chance I can be pregnant? Can plan b effect me longer ?
