Sti? Uti?

Soooo for about two months I’d say I’ve had a lot of issues like pain when peeing, always having the need to pee but either not end up peeing or only just a little bit, extreme itchiness around my vagina and my throats been kinda sore as well. I got on some meds for a uti and didn’t do a good job taking them so I’m taking them now but I won’t have the full dosage since I didn’t finish them from the beginning but I’m worried about whether it’s actually a sti or std and not a uti... I’m really nervous and don’t know what to do:(
