"so it was my first time having sex and i it was unplanned and i wasnt on birth control (which was dumb on my part, and i&#039;m starting it now) but anyways, i had sex and the condom broke but he didn&#039;t tell me till the third day. this pill is only effective for 72 hours and i took it on the 65th hour, and i was stressing because i didn&#039;t think it was going to work but believe me don&#039;t stress the pill worked. my period came today and i&#039;m so so happy, i was stressed because i thought it wasn&#039;t going to be as effective as it may have been if i took it on the first or second day but thankfully it worked."
