Hi Rae

The symptoms you are having could be caused by many things including a change of position. The kicking you are feeling down low could be kicking but it could be head butts. The only way I could tell for sure which way your baby is would be to feel your tummy, or to somehow teach you how to feel your own tummy. Sometimes you can get an idea of the baby’s position by using a Doppler.
Heavier discharge could be related to the kicks to the cervix. Providing it is not smelly or itchy then that is nothing to worry about.
One last thing. I am a big believer in a woman’s instincts, so if you still feel something is wrong go and get it checked.
