well, you could be, but it may be too early to tell by a preg test yet. I would advise waiting a few days, horrible ikno!!
I took a test the day i was due, day 30 it was a faint positive! The next day i went to see my consultant as i was starting fertility treatment, they did a test and the hospital dip test was negative! two more home tests over the wk were positive, she is nearly 6 now x
So u can get false negtives as its too early but not false positives, as the only thing that will give u that pink line is hcg preg hormone in the pee.
Good luck and i hope u get the result u are hoping for!! xx
