I had a baby last March and breastfed until September. I got one period on November 25. I did not get another. I did a few pregnancy tests throughout January but they were all negative. I did a C l e a r b l u e test yesterday and it was positive. Conception was in the last 1-2 weeks therefore pregnant 3-4 weeks How long am I pregnant? Do I go on last period date even though I only had one since I had my last baby or is the C l e a r b l u e test more likely to be accurate?
