Anyone use Accumed hcg test strips??

Charity

Are they accurate?? Has anyone ever had a false positive? We’ve been trying awhile, I finally broke down and ordered opk and hcg test strips, they came today and I decided to go ahead and try an hcg strip cause my boobs have been very sore for a few days now and it came up positive right away, I still have 4 days till AF is due!! What do you guys think??
