After a 2 months miscarraige how long is the HCG present in the urine.? - urine alarm

They say it depends on how you were pregnant? (2 months). Well, it has since July, I had a miscarraige and I assume that an opportunity had been in October. I ask because I'm having a false alarm, if I my urine. Thank you for your help!
