Becky

Help me out ladies. I am 28w4d and this morning when i went to the toilet i had this discharge wich was a lot

Wich i never had that before.

After 5 hours i went again in toilet and had this.

Is this mucus plug? I am carrying twins and i already have an preventative cervlage on. I already message my docktor since this morning but no response yet.
