I need help

Ma

Ok I'll give you guys the back story. I was lifeguarding and we called break. I stood up and started walking, all of a sudden I felt like I was peeing my pants. I rushed to the bathroom and it was blood. Not just a little, like I ruined my swim bottoms and it was going down my leg. I sat on the toilet and a long blood string, I'm thinking a blood clot. It kept coming out and it reminded me of syrup a little bit. Well I get out of work because it was embarassing and I got cramps bad. Well I drove thirty minutes home and when I got out of the vehicle, the blood was already on my shorts. I know it's a heavy period now but I'm on the implant. I've been on it for around three months now.
