Could I be pregnant

I have been thinking recently that I could be pregnant my last period wasn’t normal at all no constant flow more like spotting on and off and it only lasted maybe 4 days and ive been having dreams that I’m pregnant I’m not the person that wakes up every 30 min to pee and recently I get up at least 3 times throughout the night to pee when usually I sleep all night without getting up to pee and ive been very nauseous not any vomiting yet just nausea and I know it’s weird but I kinda actually feel pregnant idk if it’s just how I feel or if I’m just paranoid don’t get me wrong I would love to be a mom but at this time it’s not in my game plan but if I am I will be the best mom I can be I haven’t taken a test yet cuz I haven’t missed a period I’m suppose to start again in 6 days and if I dont start then I will take a test please help
