Hi there! New to this app, pretty cool! I tested this morning at 11dpo after noticing some brown specks in my cm. (I believe I implanted yesterday as I had back pain and cramping throughout the day, which would've caused that. ) pic was taken within 5mins of testing. I would say it was an indent, but the line is a faint pink in person. I tweaked it to see if it's still visible and it is. AF is due on weds. I plan to test again tomorrow and if I'm out, I'm out. We are NTNP  right now and we're actually planning to TTC at the end of next year.
