Cervical mucus is a natural part of the female reproductive system 💜 It’s caused by increased levels of the main female sex hormone, estrogen. Throughout the menstrual cycle, the amount and consistency of cervical mucus changes, as hormone levels increase and decrease. It’s common to find cervical mucus in underwear, or when you wipe after using the toilet 🧻 #fyp #cervicalmucus #femalereproductivesystem #estrogen
