Steph • Cautiously Expecting our rainbow #1 after a devastating mmc in February 2014.
I am between 10&11dpo I tested today with a wondfo, usually the strip is stark white within 5minutes other than the control line, this am I tested and though I can't say for sure I think I saw a shadow.... I changed the contrast on my photo editor as well... Opinions pleaseeee
