Too old to be pregnant?

I am 47 years old. I recently experienced the most intense GI problems in the last month. I’m just recovering from almost 2 weeks of no solid foods. I have been experiencing some pretty nasty PMS symptoms. However, last week I started getting a funny taste in mouth after brushing my teeth. In the last 3 days, my gums have been swollen and very sensitive to my toothbrush.

I also have a steady lower backache and very sensitive nipples. I’ve been pretty nauseous the last 2 days, light-headed, and am now 4 days past my steady, normal, period due date.

My 39 year old boyfriend and I have a very active sex life. We are both monogamous to each other and never use condoms because he had a vasectomy 19 years ago. He has not “pulled out” for over a year now and we’ve been together over a year and a half.

I know it may sound crazy but I’m wondering if there is a possibility that I am pregnant. Idk?
