"I thought I was coming down with a cold or that I'd become fucking gluten allergic or something."

"I was feeling really sick and then I thought that I was getting my period cause it was approaching that time of the month. The time never came. I was single and on the pill so I thought I was safe, but it turns out I'm one of the 2%. So what I got was an appointment at a doctors office to take care of it."

Helen, 24, Sweden

Editors note: The 2% is referencing the chances to get pregnant while on the pill. The pill is not a 100% secure in preventing pregnancy.
