So on the 20th, 5 days ago I light pink discharge which I thought could be implantation (see pic)

Than it started getting a bit darker as the days went by but not blood blood, not my usual period and I didnt feel like I have my period…anyways 4 days later on the 24th I thought ok my period is definitely here because I started seeing blood but with clots! Which is a first for me! I was a bit worried… i passed about 6/7 clots as seen in the pictures. My blood was very bright as well. Im feeling fatigue and just not myself.. what could this be? The blood has stopped it was literally just for a few hrs that I experienced this, its like something burst and i can feel the clots coming out. I will be booking bloodwork and an ultrasound. Thanks for reading
