My period was 9 days late and it is now extremely watery and heavy with very large clumps, I've leaked through 2 pairs of pants and pads within 2 hours. this isn't normal for me and I'm having a lot of pains in my abdomen, back and vagina, it feels like its going to fall out. Has anyone experienced this? Am I having a miscarriage? Should I go to the hospital? Really stressing about it...
