Emily

Hey ladies, yesterday I took a frer at 6pm and got a faint positive. With how frer are I didn’t believe it so I dipped another in the same urine and it also showed a line. Tested again at 7:30pm and the line was darker! I was so excited and thought this finally might be it as I’m on cycle 12 of ttc my double rainbow. Was excited to test again this morning but you could barley see the line, my urine was pretty concentrated so that wouldn’t be the issue. Just wondering if this has happen to anyone and they ended up being pregnant or I should wrap it up to egg not sticking. I know it’s very early, but it deff wasn’t a evap line. Husband and daughter both saw it clearly.
