Help please!!

I have this app and another app for tracking my cycle, etc. Weve been ttc for about 4 months and no results. I just recently downloaded the second app and this app shows my Ovulation isn't until Friday. My other app says it was yesterday. I had slight bleeding after bd today which isn't normal at all. Could this app be wrong. And could that have been implantation bleeding?

I hope I dont sound ridiculous..
