I found out i was pregnant 1 week ago and have had previous miscarriages in the past where they found a empty sac, im so scared for wed as I will be 7 weeks then and hopefully it wont be a empty sac and there will be a embro. I have done 6 tests now and all are positive and the weeks in the clear blue have changed from 1-2 to 2-3. Is it normal to have no symptoms? All i have is tiredness.
