Hi! I am a scientist and cant' figure out my results. I am 5 days late for my period, think I had pink spotting implantation bleeding almost 2 weeks ago now, and had a light positive hpt on thursday morning. I travelled that day, and yesterday the line was fainter. I did a blood test at a lab (i'm abroad so not sure how accurate the tests are) and came back hcg of 2. today, i did a clearblue test, and went back to sleep, initially, for first few minutes there was nothing then two hours later there is a clear positive line. Am I pregnant?
