Af hasn’t showed!?! Too nervous to test

AF is due today and hasn’t shown up, I have had bad hip pain all this week, it feels like my hips ate being stretched apart, when sleeping at night I’m tossing back and forth due to the uncomfortableness of my hips. The pain isn’t as bad today, but I woke up a little bit nauseous, I’ve also been super tired, i have also just been feeling off. I’m going to give it a few days and I’ll see what happens. Last 3 years my period was irregular I would go months without having a period. Than in June I bled badly, it was heavy..... like I thought I was going to die, than it became regular again. I was stressed earlier this month, but I’ve calmed down a lot since then. So I’m not sure if it is stress keeping it away. My dog has also been glued to me a lot more than usual. Could this finally be my month? I mean we’ve been trying for 4 years. We had a miscarriage last year but it was a stressful time, so I’m not sure exactly how I felt. I have two older kids from a previous relationship. It’s been almost 6 years since I’ve been pregnant. Could I possibly be???
