Everyday foods that could stop you from falling pregnant!

Caffeine - The stimulant in coffee affects a woman's ovulation because it changes hormone levels, which directly affects trying to conceive. (How am I to survive without my coffee or tea? Sob! Rooibos it is then.)

Soy – "For those trying to conceive, the excess oestrogen activity (from soybeans) is enough to induce a hormone imbalance that may affect egg production and ovulation," write the authors of Getting Pregnant: What You Need To Know Right Now. (Luckily I'm not a fan of soy despite my mother's attempts to get me to lay off the dairy.)

Peas - Apparently there is a natural chemical in peas called m-xylohydroquinone that can prevent pregnancy. (Hmmm, I do like peas but I suppose I could survive without them.)

Peanut butter - Peanut butter has the ability to deplete calcium absorption. According to Charles Stuart Platkin it "contains oxalate which combines with calcium to form calcium oxalate and thus prevent its absorption". Calcium is essential for your baby to develop and grow so cutting down on the PB is probably a good idea. (What?! No more peanut butter! That is a travesty of epic proportions!).
