I just need someones opinion my period was due Monday so 5 days late so far going on 6. I took a dollar store test last Saturday, a first response Tuesday and another Dollar store test thiS Thursday all Negative. How long should i wait before taking another. Also i had a miscarriage December 18th. Not too sure if i should be overly worried or if this is normal..
