When my husband and I were TTC, I was using *~fancy~* expensive pregnancy tests each month, thinking they would provide me with the most accurate results. I then opted to buy in bulk and try these strips out first, and I am so glad I did! I'll admit I was a little obsessive, and started testing 7 DPO even though I knew the likelihood of a positive at that stage was near-impossible... but imagine my shock when I saw the faintest of a line at only 10 DPO! And then another... and another... and another! These little strips might not look like much, but they give results!
