Waking up with nausea and acid reflux?

So, for a week now I’ve been waking up with in the middle of the night with nausea and sometimes acid reflux along with it. I feel like I have to burp all of the time. I also am pretty sure I have bronchitis, so honestly I don’t know if that’s the cause? I don’t really snack before bed and nothing has changed with my medications. (Birth control and antidepressant) I have been coughing a lot and can’t even stomach the taste of cough drops. Eating doesn’t help either. I’ve been on birth control for about 4 months, and the last pack I had my period on the placebo pills so I don’t think I’m pregnant. I’m still super confused though.
