My period was supposed to start the 7th now it's the 14th. I have took 8 home pregnancy test and all have a faint line. I went to a free health center to take the quick clear 2 pregnancy test, but before I went a drink almost a gallon of water for a "clear ultrasound", but they tested me and it came up negative so they would not give me a ultrasound. They sent me home with 4 I have took three and they all have a faint line. Please help.
