Hi I ve had 2 scans before 5 weeks the most recent shows the sac has doubled in size since the last scan & has a yolk sac. Their said their was some blood in the cervix & the sac looks abit irregular she did tell me this could be normal for being 5 weeks. All through this I ve had brown blood and I m having more red & pink looking blood with a few clots when I urinate. I m not dripping blood or soaking pads just when I wipe & small amount in pad. I ve had some period like pain also. I ve also had a urine test done & I ve got white blood cells in it I m not sure if this is Relates. Can u help.
