Okay background knowledge, I'm 22 years old I typically have a pretty heavy flow that lasts 4-5 days it's been this way since I was 13. My last heavy period was may 12 lasting until may 17. But my recent period for June was the 9th lasted until the tenth and it was basically not even there I kept freaking out thinking I was leaking or what not but I never actually used a full tampon. Maybe that's tmi but I'm just trying to figure out what it could be. I read online they say it could be implantation bleeding but how can you tell the difference? The only other "symptom" I would say would be I am frequently urinating. So is this normal or should I test?
