So I took a pregnancy test on Monday and I saw a faint positive but I was a blue dye test so I was iffy. I also took a $ test the same day and it came back negative. On Tuesday , I took another and saw another vvvvvfl. Then on Wednesday, I took a clear blue and $ store test and saw faint but clear positives. Yesterday (Thursday) I took another clear blue and there was a positive, it just seemed fainter than Wednesday. So I went and got my blood drawn yesterday and I called this morning and they said the results were indeterminate and to come back in 2-4 days. AF is due tomorrow. 8/26

Has anyone else had this happen and what was the outcome? I had a miscarriage back in February and although I know there's nothing I can do, I'm so worried about it happening once again. I'm also confused as to what the results of the blood test are. Any advice would be great! Thank you.
