Acid reflux

I've been up all night with acid reflux and it's not going away. I am 17 dpo since it is after 12 am. & no period yet.  I have veins on my stomach that's more prominent and they are really blue. I'm also having white discharge coming out of my nipples. Could I be pregnant? Has anyone else had this? Please let me know. I will be thankful for anyone's answer on what they think.
