I just confirmed my pregnancy today! I missed my period by about 5 days.
Last night, I used one pregnancy kit from Guardian. It turned out positive (clear lines in the test and result window)
Then I drove out to get another kit by Predictor (wanted to get Clearblue but nowhere to be found hee). That one, I got a faint line, so I wasnt very sure.
This morning, I woke up with a heavy bladder and decided to use the extra kit from Guardian again and it was clearly positive again.
This time, hubby and I went to the doctor, and he confirmed I am 4 weeks pregnant. EDD is 18th July 2011
From what I've read, even if it's a faint line, its still positive.
But you could just go to the dr to confirm it!
Just tell them, you wanna do a pregnancy test.
Good luck! KEeep in touch!
