Not all women get cravings and there is no real scientific evidence as to why some women do. It’s possible that your body is trying to tell you that you’re lacking in vitamins or minerals but if you’re craving gherkins dipped in ice-cream that might be an unlikely explanation! It’s also possible that it’s your hormones playing tricks on you.
It’s usually fine to indulge in your cravings without any real cause for concern but occasionally women report cravings for non-food items such as chalk. This is called Pica and you should speak with your doctor or midwife if you find yourself salivating over soap.
Eating non-food items can be harmful to you and your baby, sometimes such cravings result from an underlying physical or psychological problem and just speaking with a medical professional may help you manage things in a healthier way.
While bizarre food choices can make for funny pregnancy anecdotes remember that a nutritionally balanced diet with the occasional treat is your best menu mantra.
