Irregular periods...

Chloe

So I have irregular periods but they do stay within a 30 day cycle, and usually either come a few days early or a few days late. I’m currently 15 days late. I last had sex on the 11th, 15th and 19th of feb.. but I’m not sure when I should be testing? Can someone help me out just a little bit... I have also taken a few tests and all have come back negative, so I’m not sure if I’m testing to early...
