I only have my period for 3-5 days every month, and I haven't been on any hormonal birth control for almost 3 years. I had been on the pill for a few months (in the past), and the Nuva Ring for about a year (the last BC I used). I have also spent nearly a year using the pull-out method. (I know it's totally ridiculous, not looking for judgement.) I have never used a pregnancy test, never had a reason to. I am 25 now, does the length of my period affect my fertility at all??
