Hi doc m 20 yrs old nd I hv a

Patient: Hi doc m 20 yrs old nd I hv a 6 month old daughter, I am currently on a 3 month injection as a contraception. Now I hv a problem I’ve had my period for over 14 days now, ts not heavy bleeding bt nw m starting to notice bad odour on the blood nd the colour is not bright red. Lately I had a bad stomach bug for 2days. What could this possibly mean? And can any of this be possibly a sign of pregnancy?

Doctor:
