Pregnancy tests....

Latasha • Had ectopic pregnancy of march 2010, had 3 miscarriages December 2012-march 2013 with drs help. Had a rainbow baby girl August 27, 2015 and currently pregnant again naturally. 👏🏻
Has anyone used these?? How good are they? Are they accurate? I bought these off amazon & hoping this is the only month I have to use them.
