I miscarried at 13 weeks I also have the blood disorder called HR+ ( i think that was what they called it). After the miscarriage I had no d&c and only went to the doctor to have an injection for the blood disorder. Over the last couple of years my period is all over the place, at the moment I'm two and a half weeks late. I'm not pregant but i get sore boobs major outbreak of pimples and white mucus during the time my period is due, then a couple of days I get my peried. A year after we tried to get pregant with no luck. Have not been back to doctor but know see a naturepath and she has told me that I have a hormonal in balance and I'm on a pill to try to fix that. Could my misscarriage have cause this as they were fairly regular before.
