Potentially, what I would say is wait till your first doctor's appointment and when they give you an ultrasound they will be able to tell you exactly how far along you are but sometimes you can have a darker test if you have high hgc levels or multiples❤️
You could be! Could is the keyword, the closest confirmation you'll get is from the doctors, but even that is an estimate ultimately.
I don't think this is an indication of anything, could be just naturally high hormone levels in your urine.
