Implantation bleeding or messed up hormones

[okmomma]

I mc'd in june, had my first AF in July then started ttc. We didn't use OPK's but I assume I am 5-6 dpo (CD23). AF isn't due for another 8-9 days. Pre mc my cycle length was 29-31 days and last month was 33 days. This morning when I went the bathroom I had pink on the toilet paper. I had a little brownish discharge after, not even enough for a pantyliner. Before my 1st AF post mc, I spotted for about 6 days, but it was always red or brown blood. Could it be implantation bleeding or just my hormones playing a mean trick on me?
