Chemical pregnancy effecting cycle

Alright ladies, for those of you who have had a chemical pregnancy, did it throw off your entire following cycle? AF isn't due until the 22 or 23 but when I wiped today, there was blood. My cycles are usually 27 days long, I'm only on cd 22 or 23. DH and I were ttc this cycle, so I'm really confused on if my cycle is messed up or what. Any help is appreciated. Thanks ladies!
