Miscarriage or no?

So about a month ago I had a pregnancy test with a faint line and took a second one and it was negative so I chopped it up as a negative, then on Sunday I started my period and it was super heavy I’ve never had heavy period in my life and I’m 26 well also I chopped it up as a heavy period so I just went on with my life but after thinking about it and googling it extensively I saw pictures of large blood clots( what I thought they were) I had one very large one and I would bleed through a tampon and a pad in about 3-4 hours (that’s having both on) so I come to see what everyone thinks... I didn’t take an pictures due to me thinking it was my very first heavy period.. what does everyone think?
