We fooled around on march 22 and ejaculated near her vagina but did not have any penetration. Now she had her period on march 26 and it was a normal period it last 4 days. Now the whole montj og april she didnt get her period and its may and still doest have. She doesnt have any signs of pms or pregnancy either. Im sure we diddnt fooled around after her period. Is there something wrong?
