I took a pregnancy test on cycle day 30 (I typically start my period on day 27) it was positive with dark lines. I took a second one that next which was digital which was also positive. I've had very sore breasts for a week before that and still have them. Today, cycle day 36 I took another test just to be sure (I had a chemical pregnancy two months ago). The line was very faint. Is this a bad sign? Should I expect to be miscarrying again or is it possible I just didn't get enough pee on the stick or something like that. It was FMU all three times but I didn't pee very much this morning and feel a bit dehydrated. I am not bleeding. I've had off and on mild cramping all week since I found out which I thought was normal. The test I took today was a rapid response test and the first one was an early response test if that matters.
