I'm going crazy!!! These stupid tests!

Heather

These are all positive and initially I took the test and they were positive the day I took them prob one day apart each. I even took them apart cause I though I lost my marbles. Then I take FR which I didn't really wait much longer for but did it anyways and did it mid day and it was like maybe a line but probably not? Wtf is going on.. I want to scream! I don't even know when my period is due but I spent all night throwing up... and everything else that comes along with pregnancy. I miscarried a year ago... and I haven't gotten a positive since including on the blue dye. HELP!
