I am 32 female and 14 weeks pregnancy. This is my first pregnancy and it is normal pregnancy. I had severe vomiting for 24 hours at 12 weeks pregnancy till then everything was fine. The next day I found blood in my mucus I went for NT scan and it was normal. My placenta is low reaching upto the margins of internal os. After few days again I found little blood in my mucus and then I got clear discharge. I thought it is normal and did not report my doctor. Yesterday again I found little blood in my mucus and today again clear discharge. Is this a sign of possible miscarriage?
