13dpo At due tomorrow and had pink in cm

[MrsHopefull18]

Need some advice. I am due af tomorrow only my 2nd period after stopping the pill. I believe cycle is maybe 28 or 30 days not 100 per cent sure. Could the pink cm be implantation or do we reckon a start of my AF. Can implantation happen at 13dpo. I don't feel like my period is coming. And my sore boobs have now gone anyone had similar?

Best thing to do is an FRER. If you're due tomorrow it should hopefully pick up pregnancy hormones. You've only just come off the pill so bleeding could be down to that. It takes a while to go back to normal. Only a test will tell!
