What would you do?

My boyfriend and I are steady and have been for 4+ years, but he is SUPER paranoid about accidental pregnancy, so I was on birth control and we use condoms. Recently, my insurance switched so I am no longer taking BC, but every time a condom is still used. Since off the pill I have had irregular periods like every 2 or 3 months. I quit 6 months ago. In the meantime I just wait for it to come month after month. Has anyone else ever experienced this? Should I get a test every once and awhile to just be sure I’m not pregnant? Open to suggestions...
