TTC-bleeding

Meagan

We are TTC Babe#1. I had my first AF after more than 6 years of not cycling (4 being on depo). We believe I ovulated (ultrasound showed very large follicles) and had sex on day 2-3 of my ovulation days. Ovulation was on March 30-april 1. Throughout the day yesterday this happened. Is this implantation bleeding or just my body trying to prepare for another cycle?
