So this month was my first time ovulating, I had my first period started June 29th and lasted until July 2nd (4 days) I didn't ovulate 14 days after that like all the apps said I should it was an additional week before my test said I was ovulating (somewhere around 21 days later) now my period is almost 7 days late... I did bleed a little right after sex and thought I was my period but it stoped after I cleaned up. I've taken a test and there was no faint line or anything. Could I be pregnant or since I ovulate later does that mean my period starts later and not on the same day every month??
