Hi, I missed my period last month post Wisdom Teeth surgery. I ve had my period since the last time I had sex, but not since my surgery. I m due next week, so I m hoping for the best. Is it possible to skip periods? I had the surgery, and went off my birth control meds at the same time. It was a rather stressful surgery, and I was on a lot of pain medication afterward for about a week. Would these circumstances explain the skipped cycle or am I pregnant somehow? I haven t had any pregnancy symptoms. What sorts of illnesses coincide with missed periods? I haven t felt sick at all.
