This makes the second test I've done and a BFN. :( period is late by 4 days.. no signs of AF, but I swear I've had symptoms of pregnancy. Sore breast, tired, nausea, back pain. I'm 18 DPO, it may have been later I don't know for sure, but <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> says it was 18 days ago. I'm just honestly giving up hope. :( someone tell me they've had this but came out with a positive in the end.
