My husband got a vasectomy 11 months ago. his first specimen was all clear, but he never went back for his second. can i still get pregnant?

Chances are very low: Chances are very low but possible. I suggest a second sample.

Yes: Unfortunately, most all forms of birth control have a failure rate -- even bilateral tubal ligation and vasectomy. For instance, there could be an "accessory vas deferens" on one side, giving your husband 3. When he had a "successful vasectomy" with 2 vas specimens confirmed, bam!, you're pregnant. Make sure his semenalysis shows no sperm present -- not even dead forms. Then you'll know for sure.
