14 dpo and I took a test this morning. I already posted on here but only got a few replies. I ordered them off Amazon so I could have a lot to test everyday but I had some cramping and back pain about a week ago and this morning I had a really upset stomach. the test I took has a while test line pretty much which I have never seen! what does it mean? period was supposed to start today and it's always on time and I always have cramping the day it is starting but I had nothing and I don't feel anymore pain so far.
