So one night had sex unprotected and my bf released in me. Went to get pill next day, later that evening. Week later cycle came bled for 2 weeks.. A week later feeling fine and cycle didnt come on usual date [assuming because it came way earlier after pill]. After counting from that last cycle I am a week late for a cycle. In between that breast has gotten bigger hurting and sore. Been feeling cramps as if its coming and it hasnt. Minor sympyoms of cravings, peeing, and vagina feeling weird.. Have taken 2 preg test and both negative results. I dont know whats going on and feel like I may be preggers.. Anyone can relate and knows what this could be??? Pill or possible pregnancy?
