How often do women get pregnant after their husbands had a vasectomy???
It happens less than 1% of the time, if the vasectomy was over 6 months ago. If he never went back to get a sperm count done, then the chances are a lot greater, because some sperm an still linger in the tubes. I doubt you are pregnant. I think you are just having some kind of hormonal issue. My girlfriend went though that even though she has never had children. This is rare with women that are only 35, and never had kids. She had to get a hysterectomy to make the problem go away. I think maybe you should see a doctor, about your hormones. We were both sterilized long before we met, and didn’t want kids anyway, so there was no loss.
