Fertility isn't just about looking fat or skinny, you retards. It's a byproduct of a regular menstrual cycle with timely ovulation, balanced levels of FSH, LH, Progesterone, TSH, hCG and enough ovarian reserves (the number of healthy eggs in a woman's ovaries that can potentially be fertilized). 

Go try having kids and before that, get a hormone panel done, you will know how fertile you are. With that being said, obese women who shame skinny women because they think their "fats" make them fertile is so funny, a body fat around 20-22% is good enough for pregnancy. You don't have be hippoes with a big belly to be pregnant.
