Is this real?

Hello! So I finally got my positive pregnancy test after waiting so long🥹🥹 however before I get too excited I’m trying to taper my expectations on if it’s a chemical pregnancy, will end in miscarriage, etc.

I don’t really know what a chemical pregnancy is exactly, but I did want to ask in here. Would my pregnancy test lines be getting fainter or darker if I had a chemical pregnancy test? My tests seem to be getting darker and darker by the day but I just want to make sure this is real.
