Trigger or real bfp? 5dp5dt

I started testing way too early at 3dp5dt, 10 days past trigger and got a faint positive. I was skeptical knowing it could be trigger. I’ve continued to test twice a day and the lines seem exactly the same, not getting lighter or darker so I’m confused. The last test is this morning at 12 days past trigger. This mornings test has definitely dried darker than the rest but I know that doesn’t mean much.

Any thoughts or experiences to share? My anxiety is through the roof because this was our only embryo.
