I have taken three pregnancy tests all show negative but my period is now ten days late.
I do have a slightly abnormal cycle but is always normal for being abnormal,it has been 22 days since ovulation and sex.
I am also experiencing a slightly clear discharge fromnipple when pressured is applied.
Could I be pregnant and it be toearly to show up?

Yes you could. You could also be stressing about it too and that might be holding your period back. I would go to the dr and get a blood test done.
