Me and me partner have been trying for a year and a half with not a glimmer of hope. Until Saturday. My period was due so I took a first response - it was POSITIVE!! So I went and got a CBD and it was NEGATIVE. Im so confused and going crazy. Every morning since I've either taken a first response or a clear blue (not digital). Every first response has been positive and any other brand is negative. Has anyone experienced this and been pregnant ? My period is now 4 days late and I'm usually like clockwork so that is giving me some hope.. HELP :(
