Hey so I’m really scared!!!

I had a pregnancy scare a few months ago and got my period. But recently I’ve been feeling strange today I woke up feeling awful and I swear I almost threw up a lung. But a weird thing that’s been going on for a few days is that when I pee there’s this weird tingling feeling that I kinda associate as pain but it doesn’t hurt it just feels weird like I’m being poked down there. This all started when I got my period this week which has been weird too! There’s a lot of bleeding when my periods are often heavy at first but they tail off a bit when I get to day three but they’ve been constant. Is this just me developing or should I be concerned.Anyone know what’s going on. And please god don’t tell me I’m pregnant 😳😭
