Feeling pregnant??? 🤔🤔🤔

For some reason I’ve been feeling pregnant since last month. I got a super faint positive but still had a very STRANGE “period” that was heavy one day then super light like spotting for two days when I i last 4 days. Since then I’ve been actually feeling pregnant. Does this actually happen or am I tripping??
