Ttc need advice

So , I’m just starting out last time I got pregnant it was a accident. So like knowing there’s a goal being off birth control is making me a little anxious. What does implantation bleeding look like? Also in everyone experience is glow pretty accurate for the ovulation day ? because I’m slightly confused , my gyno said something about the 2 week mark because my last period starting date was June 6 but I always thought it was though ovulation was loser to your period . Maybe I misunderstood… moral of the story I don’t know what I’m doing 😂
