Browish discharge two days after missed period. is that normal ?

Normal cycles come every 21-35 days.: If blood comes out of your vagina in a different pattern then your cycles are not normal. If this is one time problem it may resolves on its own. If recurring then you should be evaluated. Infections & hormonal changes can cause spotting. If there is a concern for pregnancy then do a home pregnancy test . There are many options to regulate the cycle.
