Possibly pregnant or just my mind playing tricks on me?

Patient: I have had a few pregnancy symptoms but they could also be related to anxiety. I have had a little smell sensitivity, tender nipples, and frequent urination. I have taken a pregnancy test which came out to be negative. I have been on bc for five years straight. I haven’t had a period in 18 months. What are the chances of me being pregnant or is my mind playing tricks on me?

Symptoms: I have tender nipples (on a scale of 1-10 I would say 2) with a light blue vein from my chest to my nipple only on my right breast which happens to me occasionally. I have urinated 5 times today already and haven’t eaten or drank anything today; the urination is accompanied by a burning sensation which also happens occasionally. My smell sensitivity is somewhat heightened. I’m also gassy, but that too is in normal for me.
