I am enrolled in nursing school and my mmr titer came back negitive meaning I am not immune. I had to have the first shot today and wasn't told til after that I couldn't get pregnant for atleast 4 months after the shots. I get my next one in January. However, I'm ovulating today and BD two days ago. Has anyone fallen pregnant close to an MMR vaccination? If so was everything ok? Does anyone have any legit info on the effects and/or how common CRS is from the vaccinations? I'm just a super paranoid person and know it could be a possibility.
