hello thank you for trusting HCM dear along with the bowel movement mucous present in cervix may dislodge it is common in few people.but if you observe any sporting or itching or white discharge means please consult your doctor. Progesterone effects: An odorless, heavier, thick, whitish, or yellowish mucus discharge might be one of your earliest signs you are pregnant. This thick, sticky, or gummy mucus is caused by progesterone. Estrogen effects: As your pregnancy progresses during the first trimester, you might have a heavier mucus discharge. Estrogen increases the amount of mucus the inner lining of your cervix (endocervix) makes. The effect of estrogen also makes your cervical mucus feel wet and slippery, and it can look clear, milky white, creamy, or yellowish. I think I answered to your question if you have more questions feel free to ask. take care
