Any advice?

Hi everyone I just wondered if anyone could offer any advice.

I started the pill a week ago, over the past few days I have been feeling nauseas, bloated, stomach cramps, my boobs are huge, been having on and off headaches and have an unbelievable amount of white milky discharge. We had unprotected sex on 1st feb. I did a pregnancy test before I started the pill and it was negative.

Has anyone had this when starting the pill?

Thanks in advance.
