Do you have to ovulate to have a period? Because I had a period in May but my doctors days I didn’t ovulate that month fast forward to now I haven’t had my period at all it was supposed to come on 6/8 it’s currently 6/12 today is the day it was supposed to end. I was told that since I didn’t ovulate in May then I wouldn’t have a period. Is this true or what should I do ?
