Hi, In the current scenario, you should immediately contact your consultant. Presence of greyish to bloody vaginal discharge is suggestive of some intra-uterine bleeding if all local causes like erosions, polyps etc. have been excluded. A trans-vaginal/pelvic sonogram should be done to assess the state of the pregnancy and look for any hemorrhages. Please take absolute bed rest, avoid all stressful activity including sexual intercourse. A sanitary napkin and not a vaginal tampon should be used to monitor the amount and nature of the discharge. Hope this helps.
