i joined the group so i can have someone to talk to about my missed period! my husband and i have been married for almost 5 years and just started "trying" to conceive! well dummy me didn't realise my period was due about 3 days after! it's been almost 2 weeks since "the moment" and 1 week since my period was due! can I take a test this weekend?! will it be accurate?!
