"okay hey ladies! me and my boyfriend had a condom break so  i took plan b about an hour later. then, about a week later, i got a period. now this was about two weeks early but it&#039;s pretty normal for this to happen with plan b. it also is a good sign that the pill worked but it isn&#039;t a promise. so, i anxiously waited for my normal period but as that time was going by i looked into getting an iud. and now that i just got my period today, i can go back and get an iud in!!! for everyone out there who doesn&#039;t want to go through this again, i highly recommend an iud. they can come with or without hormones, are 99.9% effective, and can stay in for 3-12 years! the insertion only lasts a couple min and they are free! stay safe :)"
