I used these 7 nd 5 days before period now I'm 14 weeks these are the best when read within time frame !!

I used a cheapie $1.00 dollar store test first, when it came up positive I went the next day and bought the box of 3 FR tests lol 1 was FRER, 2nd was digital, 3rd was just a Regular FR.

FRER and then I switched to first signal (the 88 cent Wal-Mart tests) Due to an early loss in 2015 I tested once a week every week until my 8 week appointment.
