It's all down to hormones. You produce Follicle Stimulating Hormone (FSH) during the first part of your cycle that triggers your body to start the process of maturing eggs for ovulation. High levels of oestrogen are produced at this time that triggers a release of LH, Luteinizing Hormone, causing the mature egg to burst from the follicle. That is ovulation. Normally, only one egg will be large enough to burst through the follicle during ovulation but occasionally two will, which is how non-identical twins are conceived.
