Mucus Plug?

Hi mommy, Asking for insights of what do you think it was? Not able to capture some pictures of it but kanina po kasi pag hugas ko down there may egg white discharge ako. Which is ngayon lang naman nangyari sakin all throughout the pregnancy. EDD based on ultrasound : Aug. 7 2023 - 34 weeks EDD based on LMP: July 21 2023 - 37 weeks Regular menstruation din po. Di ko lang alam ano susundin, and if sa tingin nyo po ba mucus plug na yun? PS: Namili po kasi kami sa sm ng gamit ni baby, then ngayon masakit pelvic area hanggang pempem pero di naman nag hihilab yung tummy. Ngalay lang din yung lower back. Bukas po mag papacheck up din ako sa OB Please share your insights. Thank you 💗
