Additional information: Since the 2nd vaccine my menstrual cycle has been messed up. My first two periods/PMS resulted in excruciating cramping, comparable to labor contractions. Last months menstrual cycle was very short. This month I'm 2 weeks late. I've taken a pregnancy test and it's negative. I had a tubal litigation in 2015 so I didn't think it was that but I wanted to make sure. I've never had any timing issues with my periods or irregular symptoms until now. I've discussed this with many female friends who experienced similar problems after the full vaccines but there is little research available on it. Patient did not receive other vaccine in four weeks. Patient was not receiving other medications in two weeks. Patient did not received treatment for AE.
