UPDATE Pregnant?

I just got the hormonal iud a month and a half ago, had my period for 10 days and now I’m about 2 days late for my period. I know a lot of people don’t get their period with the mirena but i thought it might be weird that I’ve only had one period since getting it. How concerned should i be?? I don’t have any pregnancy symptoms, but i just want to know if i should immediately go out and buy a test or just chill out. I waited the appropriate amount of time until i had sex without a condom and took my birth control pills for the first week

Update: got my period guys lol, but i had ordered pregnancy tests on amazon the night before so now I have 20 test strips i don’t know what to do with😂
