I'm currently four days late on my period I've had cramping here and there but have never been late before except with my two kids I took a test and it said negative I was also on mirena for three months and got it took out due to complications its been almost two years and still haven't hot pregnant or been late until now any advice

Yes, no way to test at 4 days late, you have to wait about another 10 days and if not period still do the test first thing in the morning when you awake.

But then a missed or late period is also something that just happens sometimes
