This morning was the day my period was due. It hasn’t come but I also took a plan b earlier this month so the delay was expected. Being the worrier I am I took a test today. I woke up at 5 am to use first morning pee. I waited 3 minutes and negative. waited till 20 minutes and still negative. So I put it back into the box and threw it away. When I woke up 3 hours later out of my own curiosity I picked the test up and looked at it again and i was so confused. A greyish thick line showed up where the positive line should be. I know clear blues are notorious for this but I am really freaking out. Anyone have experience with this? I bought a digital one and will be testing again in the morning!
