To test or not to test!

Katie • I`m almost mid 20s owing my own house with my boyfriend of over 5 years we finally have had our dreams come true. 💖 Isabelle Ivy kirtland 💖
I haven't had a proper period since March 25th but I am so irregular. I had 5 days of brown discharge this month. Should I get a test? I am in a secure relationship living with my boyfriend we have said when it happens it happens. What are people's thoughts?
