I've been testing for a few days now and have had all negative results. I was supposed to start yesterday but no sign of it. I am crampy and moody. I also have had bad bowel movements to say the least and peeing a million times a day. I tested this morning and at first it seemed like a negative but I thought maybe there was a second line but there looked to be some pee on the window so it was hard to see. I let it sit for about an hour and looked at it again and there is definitely a second line. I am going to test again tomorrow of course to verify and see if the lines show up right away but wanted to know if it could be positive for sure.
