I'm 42yrs old & my husband had a vasectomy 15yrs ago so I know 100% that I am not pregnant. My periods have always been on time with no problems but this time round things are very different, I started on Thursday morning with no more than a table spoon full by the evening it had stopped. Friday evening I had a couple of spots then nothing till Sunday again a couple of spots. The strange thing is I have been experiencing tummy cramps the whole time. Can anyone help? I've been unable to find any answer for this
