Bloody mornings?

Jessica
A week ago I bled a small amount after sex. Saw my Doc did u/s. She said it was just from sex. Through out the day it faded away. Next morning red blood & a clot. Doc has me come in again. Cervix is still closed babies heart rate is still good but she put me on bed rest for mow. Every morning now it's red blood first thing then fades to brown and pink then gone in the afternoon. WTH is going on??
