I normally have 26-28 day cycles, today was CD27 and 15Dpo. Been having AF like cramping for the last 2 days which is very unusual for me, normally cramping only starts once AF has arrived. This afternoon finally I got some pink tinged CM so I thought ok AF is here and put on a pad. Normally it becomes red quite quickly but since then nothing except a bit more pink CM. The cramps are quite intense though and really bad lower back pain too.
Has anyone ever had this? I thought it would be too late for implantation bleeding right?
I did a hpt test on 13dpo and it was BFN.
Really not sure what's happening, my period is never like this? Thanks!
