Hi Keisha, I personally would wait and keep testing every week from my own experience. I kept getting negative results when i was first pregnant with my daughter and it wasnt until i had missed 3 periods that i finally got a positive. I know how frustrating this is.
My husband and i are ttc our 2nd child with no luck at the moment-i was recently 5 weeks late and did tests which were negative but i still thought i had a glimmer of hope as this happened before when i was expecting my daughter but unfortunately the dreaded AF appeared last night so i guess thats my answer set in stone.
Leave it a week hun and test again, also are you taking folic acid? This is important while you are ttc.
