Go to the hospital ?

My period came yesterday a little late and I experienced horrible cramps and back pain to the point I felt like I was dying I was super weak I could barely move and constantly felt like throwing up until I finally got the strength to get some medicine and all the medicine did what take away some of the pain so I could finally relax to sleep I had been up all night battling the pain and nausea and now I’m not in pain thanks to the medicine I took but I’m still extremely dizzy feeling pains in the middle of my stomach I’m really tired and I’ve been bleeding really really hard and it’s a really really deep red I looked it up earlier and google said low iron but then when I looked up more of what I’m feeling it says ectopic pregnancy idk what’s happening and my boyfriends mother keeps asking if I’m pregnant out of the blue I think something may be wrong should I wait it out or go to the hospital?
