Fertility

Jasmine • Hi I`m 23 yrs old and I would just like to know my fertility peaks so I can somewhat stay clear until I`m ready.
Okay I have a small question.. I was told that the faster your hair and nails grow the fertile you must or may be.. Ok everyone around me continues to get pregnant but I never do even with the small slip ups me and my bf have had.. I Thank God because I'm not ready but is it true that your hair and nails are signs of how fertile an individual may be or is that an old wives tale? Because I've always had fast growing and long hair/nails ... I'm only curious
