Implantation bleeding? Pics

Okay so my cycles are very regular. They’re usually 35 days long. I’ve been TTC for 12 months now. Last month I had an HSG done. This is my first cycle since, and I was ttc this cycle before trying Clomid. Doctor said if I got my period to begin the Clomid pills. Well last night (cycle day 28) and 7dpo, I started bleeding. I immediately cried like a baby. Thinking I was out for the month. But color and flow are not typical period like.... Light pink and brown. This morning same thing. I had a tampon in and when I went to the bathroom there wasn’t much on it. Implantation bleeding or early period? Thoughts??
