okay my periods are never normal...this time it was sept 22nd it started and ended sept 26th. i have been pregnant before twice, 2 miscarriages one at 28 weeks and the second at 5 weeks. so im pretty familiar with the symptoms. i've had lower back pain, nausea(without vomit) headaches, 2 days last week i had cramping in my abdomen, white discharge lining my vagina(sorry if thats TMI), and my nipples tingle when i touch them. however having noted all that, i am early for my period, its not due til the 20th of oct . i took one pregnancy test that had very light positve lines , and 3 that said negative...so im not sure whats going on???anyone with similar story. any info would be appreciated. thank you.
