... there are other ways it could happen and it could get inside of me. it is now the 15th and I have bloating, cramps, and diarrhea. I know I probably sound stupid and I personally am very educated on sex, but I honestly rarely have it, so I'm not completely sure the normal symptoms of Plan B's. I also have PCOS and have not had a period in 4 months so it's very hard to track my period. Please let me know if I should genuinely worry?
