question: I have been having pregnancy for several weeks. This would be by 7th pregnancy (I have 3 children). One week after what I believe was implantation I had a ChatDoctor quantitative test that said 1. My symptoms have not gone away, and some others have become noticed. The doctor says I have a problem based on all my symptoms. Is it possible for a thyroid problem to mask or hide ChatDoctor in the blood? Or could it have been too soon?
