Alright so I have been having a super weird period so I think.. I've bled three times within a month time. The first time was like an actual period and these last to times started with dark light blood and turned into heavy and then I would stop and start again. I'm cramping and also having a very "sweet" smell to my urine I'm scared to death what could this be. I have had a baby already and never had these symptoms before. Pregnancy? Uti? Help ladies
