21 DPO & 9 Days Late.

So I had my mirena removed a little over a month ago. My first period since was normal & on time. We’re TTC & did the BD all throughout the week of my predicted ovulation. I have taken 3 PTs. One @ 7dpo & used the 6 days early test & then took 2 after my 2ww & all were negative. I’m 21dpo & am 9 days late for AF. I haven’t had any symptoms other than bloating & nausea, haven’t vomited but certain smells make me sick to my stomach. Maybe I’m crazy or it’s all in my head. Anyone else had similar situations? Should I take another test? I don’t wanna get my hopes up but if I am prego I wanna know ASAP.
