Wtf is going on??

Currently 3 days late today..feeling pregnant but i also have a uti according to the doctor so i have been taking medication to clear it up. Don't have symtoms of a uti just nausous everyday and all day and have a horrible headache that wont go away i cant even be around people half the time bc my head hurts so bad.. My boobs & nipples are sore af and i am super bloated..by this point i just wanna know am i pregnant and if not where is my period?? Doesn't seem like i am getting one this month since theres only 2 days left. Ive taken several pregnancy test and got faint lines took one today from dollar tree and got a straight up negative! I dont know what the hell is wrong with me🙄🤦
