Could I be pregnant?

I have been feeling bloated like my period is about to come and I've had some cramping and even seen a white discharge last week. My breast dont feel sore like with my last baby but feel heavy and uncomfortable. I even feel full even when I know its time for me to eat something. Is the bloating part of pregnancy symptoms too? I got a negative pregnancy test yesterday and my period is due today and still nothing just heavy feeling in my belly but my breasts don’t normally feel like this. Any suggestions? I’ve been ttc for 4 months now.
