I took a pregnancy test on the 19th of January and there was a faint positive line. I tested again the next day an there was another faint positive line. So I went to the doctors and done a urine test an it come back negative so I tested again at home another four times and two were posative and two were negative. But I was still having symptoms of pregnancy so I took another urine test at doctors and it come back negative. Also I had my period (if it was a period) 11 days early but it was light and only lasted 3 days unlike my other periods. So I went back to the doctors and had a blood test and it come back posative. Would I have been pregnant when I took the first test?
