Help needed ladies.

My husband and I have been actively ttc for a couple of months now.

My periods are regular.

Today, for the first time ever when I wiped I saw brown discharge and didn't think much of it. However, couple of hours later when I went to pee again I saw it again.

Fast forward 4 hours; I went to pee again and saw the brownish discharge along with a little blood.

My period is never early, and isn't due for the next 3 days.

What exactly could this mean....?
