Were you on the pill recently and stopped using it?
No I have never take pills
Are u under a lot of stress or have u been sick? Or are you coming off any form of birth control? Before I became pregnant if I was under a bunch of stress my period would show up early. My next advice and this is how I got pregnant was download some fertility apps on your phone. My favorite was My Days fertility app it helps you keep track of your period and tells you due to your cycles when you best chances are to get pregnant and when your highest fertility days are I used my apps like they were something sacred when I was trying and after 3 months straight I conceived in January. Otherwise if your questioning wheither you are or not take some tests or head to your drs and explain to them whats up.
Thanx a lot you were really helpful, I have downloded LadyTimer app and is really cool. I will try even My days app.
