So my friend has been taking pregnancy tests and has been getting very faint lines..she went to the docs on Feb 6th and the blood work came back negative. She is still breastfeeding so hasn't got an actual period yet since she gave birth in July of last year. She decided to take a few more tests between yesterday and today and she is still getting the same result! The first one up top was her son's pee to see if it was the test brand was inaccurate. The rest of the tests are hers. What do you guys think?? (Also, she hasn't had sex since the 2nd because her husband has been in the field training)
