If it’s been 5 days or less since you had sex on the wrong day, take EC. If it was more than 5 days ago, you might want to take a pregnancy test if your next period is late. Either way, if you’re having unprotected sex on unsafe days, you might want to consider a lower maintenance method.
Still not working?
If you’re having trouble getting your fertile times right, you might want to consider a lower maintenance method like the IUD or the implant.
Like the no-hormone aspect of fertility awareness? Check out the Paragard IUD or stick with a barrier method like condoms.
