Implantation?!

Hi ladies, we are in month 2 of ttc. I'm on cd 27 and I've started spotting dark pink/light red 🙈 My cycles are usually around 33/34 and never less than 30! Iv got slight cramping too. I'm so gutted if af has turned up to surprise me a week early, but I have a teeny tiny bit of hope it could be implantation bleeding? What do you all think? Any advice is welcome 😘 Xxx
