Hi, I did a clear blue ultra early results yesterday morning with FMU and it came up positive within 2 minutes, it was a thick blue line, i’ve had all day cramping, back aches, on and off nausea, and painful nipples so i felt like i was pregnant, This morning i did a first response and it’s completely negative and i feel so upset, my period is due today so i guess i’m not going to test anyone until she comes.
