Please just help me. Dear god..

So I don’t know if I’m currently experiencing a hormonal and balance, a miscarriage, or may still possibly be pregnant and I just want to know which one you think is more probable. I’ve been experiencing very light weird spotting/discharge, and mild nausea and food aversions. I’ve also been experiencing more dizzy spells however I’ve been writing it off to my tinnitus, but now I’m really starting to question it because I haven’t had a full blown period In two months basically. My periods are typically very heavy and last eight days but so far it’s been nothing to even warrant a pad or a tampon. I’ve only been wearing pantiliners and it’s mostly only when I wipe, not much gets into the pantiliner. I haven’t taken a pregnancy test. I’ve lost about 5 pounds since my symptoms started. The last pregnancy test I took was three days after the day I would think would be when I conceived. When I had sex it was unprotected. Could I still be pregnant with my bleeding symptoms? Or do you think this is more of a miscarriage? And if neither do you think it’s just a hormonal imbalance or something else right now that’s really weird because it seems I’ve been going a week with some spotting and then a week without and then a week back on since mid December.

What do you think?
