Early period or implantation bleeding?

I’m not sure on all the terms and abbreviations but had my last period August 5-8th and had bleeding the 14th and 15th, I stopped taking birth control this month to ttc. Spotting started yesterday and it was very faintly pink and stopped til today mid afternoon no clots but light bleeding. Usually I’m very moody before I get my period but I have been in a fairly good mood, very increased appetite, slight cramps but not like usual on my period. Spotting started on 25th day of cycle. First pic is from yesterday and second is today after 4 hours using a pad, picture makes it look darker than it is. Suggestions?
