Been ttc baby number 2 since December, no luck yet. First day of my last period was March 3rd, I'm now 7 days late. Have done about 4 tests and they're all negative with no hint of a line. Thought I had very slight implantation spotting on March 22nd but clearly not 
If my period doesn't come, when will my fertile week be to ttc again? Very confused and disheartened
