Hello, Thank you for your query. *how late was the period? *did you take any pregnancy tests? Results? *did you take any medications like contraceptive pills? It could be a miscarriage but it could also be a heavy period. I recommend : -a OBGYN consult right away -an ultrasound abdomen -blood tests (complete blood count, beta hcg level, kidney and liver function tests, clotting profile) In case of a miscarriage, you need to see a doctor right away to make sure it is completed and bleeding is as expected.. If not the cause of bleeding, like a ruptured ectopic pregnancy needs to be treated immediately as it is a threat to life. Hope you feels better soon. Please let me know if there is anything else I can help you with. Wish you good health
