Help Please

So yesterday I went to the bathroom and I was spotting a little bit of bright red blood. Later that day I had brown discharge. Today this morning I went to the bathroom and a lot of blood came out and I got scared. My period ended 5 days ago, every time I look online it says pregnancy but there is no way because according to glow I’m going to ovulate in 6 days. It also says menopause but I’m only 25. I’m starting to get scared I don’t want to think it’s an std or something. Last time I had blood in my urine was when I was pregnant and since I didn’t take care of it, it ended up becoming a kidney infection. My son is 14 months so it’s been a while. I’m just scared can someone give me advice please.
