Why am I having backaches and brown spotting for 3 days and nausea but no actual period any ideas husband had a vasectomy 6 months ago really am wondering if this has anything to do with it?

maybe you have implantation bleeding or maybe this can be stress-- you should either take a hpt or go to your doctor and ask for a blood test--sometime stress play major role in women's period and we confused it being pregnant and at the same time you can experience pms but at the same time you can be pregnant-butlike i said take a hpt or go to your doctor for a blood test a blood test is more accurate than a hpt..good luck
