Helpp😢💔

So i had a couple different real faint second lines on tests over a couple of days then two days later af came.. but I'd been cramping for a week and still am cramping now. I don't normally etc cramps but it's been fairly intense. The bleeding is horrendous too , really bad thick and red! I do suffer with pcos and most of the time my periods are mostly brow so old blood but this is All red and very fresh. I'm just worried I know I could have had a chemical but what if it wasn't and was more like idk 😣 am I supposed to go hospital? I took a test not too long ago and I swear I still see I vvf line.. idk what to doo💔 this is day 3 of bleeding
