Hi, I had a really light period last month and thought nothing of it...I wasn't feeling right or good the last few days so I just decided to take a test I shouldn't have my period for another week but the test I took showed up positive it was lighter than the other line..but was there for sure...since then I have taken two more tests and they did the same...I feel very tired lightheaded to the point where I feel like passing out and a little nauseous...I started spotting brown but very light not even enough to wear a panty liner. Does anyone think I might be pregnant if so how far along and if not what's going on. Thx to any that can help or share their stories.
