You may: Occasionaly have irregular bleeding. If it is a change from the normal it may be nothing and improve next cycle or it could be due to another cause such as infection. I would check a pregnancy test to make sure and see your doc if persistant or there is associated pain. If persistant a birth control pill can be a good remedy. Good luck.
