"i took this pill about 20 hours after &quot;unprotected sex&quot;. i had absolutely no side effects for about a week, but then my breasts hurt and became enlarged, i was constantly bloated, constipated, and had horrible back pains and cramping. i was completely stressed out and scared i might be pregnant after freaking myself out reading about pregnancy signs. however, my period came today and i&#039;ve never been so happy! the flow is normal but with more cramping than usual. overall, i am very pleased with this product! it is way less expensive than a baby, and i am never having sex without protection again! but don&#039;t worry ladies..it&#039;ll be ok!"
