"i had an unprotected sex with my boyfriend on oct. 7 (a week after my period) and only got the plan b pill the next day, approximately 30 hrs later. the first 2 days i did not get any symptoms at all, but from the 3rd day on, i felt nauseous, extreme fatigue, and i have been burping a lot. 2 weeks after taking the pill, on the 24th of october, i got a really bad cramps and i would say a really light period. however it got lighter and lighter that seems to be spotting and i continue to experience symptoms. a month after the incident still no period so i took a hpt and it came out negative. fortunately after this, the symptoms starts to lessen but had a very tender breast with some cramping as well and today nov 22 i finally got my period."
