I know you can test as early as 10 DPO and get a possible +HPT. I love to test early. In 15 months I have only gotten negative results. Of course I get disappointed, but I guess if the result was postive I would be glad that I knew so early.
So, here is a list of the accuracy of early HPTs
HPT Accuracy Results Percentages: (Based on a 25mIU sensitive test)
10 dpo : 35%
11 dpo : 51%
12 dpo : 62%
13 dpo : 68%
14 dpo : 74%
15 dpo : 80%
16 dpo : 88%
17 dpo : 92%
I am only 8DPO so I still have a few days before I can possibly test. But, I will probably only use the internet cheapies for a few days and then use the FRER later on and only if I get a positive on the cheapies.
