Yes, I have considered it. However, this cycle was potentially anovulatory (weak OPK, sad temps, short cycle). Besides, with the tests right before and right after being negative, I think they are actual evaps. (But will that stop me from taking a look after the time limit? No... )
ETA: That was the early-pregnancy-tests brand... I have now seen evaps on this brand, Wondfo, and FRER (I'm sure only because I took it apart. Lesson learned there -- I will never take apart a FRER!)
apeydef, I'm sorry. If you aren't sure if you're ovulating, I'm a big fan of temping and OPKs.
