My last normal period was Mar. 20th and then I had what I think was implantation bleeding Apr. 16th I took a test Apr. 18th and was negative so I was thinking I wasnt pregnant. Then as the days went on I had more and more symptoms of pregnancy and now there is a metallic taste in my mouth and my husband actually said he smelled the metal smell. Now my question is Im not due until May 13th but would it be to soon to test if my last "normal" period was Mar. 20th????? I want soooo bad to test NOW!!!!
