In the follicular phase, the follicle is in the stage of growth and development, the follicle is relatively small, it may only be 0.9*0.7cm, which means that the follicle is in the stage of growth and development, it has not yet matured, there is no mature follicle formation, and this kind of follicle will not normally discharge the egg. As the menstrual cycle changes, the level of various sex hormones in the body gradually rises, which can promote the gradual development of follicles, and in the ovulation period, there may be mature follicles formed before the eggs can be discharged. During ovulation, the mature follicle is able to discharge an egg, and if you have unprotected sex during this period, the likelihood of pregnancy is higher.
