So nervous

Brittni
So here the thing, I've always had regular cycles always on time no problem after I had my first child I got the mirena had it for two years got it taken out in Feb of this year I started my first cycle right after no problem and have had three normal cycles since then, been trying to convince since its been out!!! The problem is AF is three days late I started testing 5 days before few faint positives and some that looked negative to me!!! I took a dollar store test the night before missed  period and morning of and both negative!!! I haven't test since then and trying to wait a full week of Missed period before I test again, I'm nervous is anyone else going through this or went through it and had good news in the end??
