its good that there were more woman with grade 4 who didnt bleed til after 28 weeks

the other question i got asked was did i have any pain???? i kept saying no cause she(midwife) asked with the bleeding
but ive had pain down there especially after walking(even short ones) didnt think anything of it so ill be asking again at my next OB appt if the pain im getting is normal but also i know what questions to ask during my U/S next week
