Hi I am unsure what is happening for me. I am late for my next period, my husband had a vasectomy 8mths ago. My periods have always been normal as clock work and I am 34yrs old could I be early in perimenopause or could I be pregnant. Have checked out symptoms of perimenopause and I don't think thats me, my mother went through it at about 39yrs, confused and unsure what to do. Did a pregnancy test yesterday arvo and was negative but not sure when to do another one, am very impatient to work out what my body is doing, hate not knowing.
