What's going on with me.

Ok, so my AF came this Thursday and for the first day and a half it was bright red then it became brown and it only last for 3 days usually my cycle last 5 days. I don't know what's wrong with me. We been ttc for 2 years now, we started clomid since April and I just don't know if this was inplantation or an actually cycle. Anybody any advice.
