Did I miscarry

Angel

So me and my SO have been TTC since we got married. I have been feeling a little off so I took a pregnancy test and it was negative. A few days later I started my AF or I thought I did but I’m not sure. I came to the bathroom and had a reddish/brown discharge in my panties but when I wiped it was light pink so I was hoping maybe it was implantation bleeding but later that day it got heavier and had big clots and was bright red so I put a tampon in assuming it was my AF. When I would change my tampon it would only have a little bit of blood on it but have lots of clots. The second day of my “AF” I had completely stopped bleeding, nothing on my tamping and when I wiped nothing was on the toilet paper. Around 3 the next day I was out doing some errands and went to pee and when I looked in the toilet the water was bright red with lots of clots in it (tried to take a pic but it was an automatic toilet) and when I wiped the toilet paper was full of blood so I put some toilet paper in my panties because I was out of liners and didn’t want to waste another tampon. When I got home it was just spotty but when I wiped I had quit bleeding again. I wore a tampon to bed last night and when I changed it it had some blood but not much. I have been cramping like my period but I have also had a headache and backache and sore nipples which is unusual for my period. Idk if I’m just going crazy or if I could have possibly miscarried or what. What do y’all think is going on? Should I go to the doctor or just wait it out?
