When I took my first test it was so faint I considered it negative I then noticed it and I'm now 26 weeks so I would say if it came in the time frame allowed its positive.
The brand I got was a cvs brand and it unfortunately had no time limit for it (but I assumed 5-10) would be good? But within 4 or 5 mins is when I saw the faint line. Hopefully I'll get some results tomorrow with AM pee
With all three of my pregnancies, I never took the test in the morning. The test say you should do so. But don't have to. I would think, wait until the day of your period to take another test. I have always used the dollar store test that cost $1.07 after tax. So the very cheap ones and got my results in ten seconds. But... good luck!!
I took a test 4 or 5 days before my period as a joke for a friend who just found out she was pregnant and mine had a really faint line. I almost fainted but mine also was in the afternoon. I took a clearblue the next morning and it said pregnant. Hope you get the resaults you want :)
& my lines on the day of my period was due we're very, I mean very dark. So I wouldn't take the test tomorrow, again wait until the 30th to take the test
