OK I have a better way to ask this question? Is it possible that I would be having a brown colored discharge all of a sudden,instead of the clean fluid I had last night ,if I had the donor with us today.and I also feel a little stomach ache... this brown colored discharge has never been there any other time that I can remember intill today in my 20 something years of ovulatin... can things start happening this fast?

No, things do not happen that fast. It may be necessary to get a physical from your doctor to find out what is going on. But this sort of thing does not happen in 24, 48, or even 72 hours.

J_9 is right things don't happen so fast, maybe tyou would be better to consult your doctor.
