Hey everyone just writing this to see if anyone has been in a similar situation to me right now!!

I am currently 2 days late, I am NEVER late, my cycles are 28 days without fail.. The past 3 or 4 days I've been having quite a fair bit of cramping with a bit of creamy white cm, almost feeling wet all the time, it honestly feels as if my period is coming I keep going to check but nothing! I've tested yesterday and today with FMU and nothing at all! Anyone had this and gone on to be pregnant? My boobs are killing me, I feel pregnant but no test to back me up. Tia x
