"on january 21, the condom broke. my boyfriend purchased it the next day. i took the pill about 18 hours later. immediately i started to experience side effects like headaches, cramps &amp; body aches. after a week my side effects was light cramping &amp; mild headaches. i got my period today ! my period usually comes round the first week of every month; so im a couple days late. i never been so happy to be in so much pain. i normally have bad cramps so this is nothing new. be patient &amp; dont stress."
