Trying to get pregnant

So I am hoping for a little help from you ladies!

I am an endometriosis patient. I just had a surgery to clean it all out in March. I am currently on a crazy cycle they’ve been 36-39 days. And this last round I ovulated on days 28-32. Well I started my period on day 33. After 7 days of sex and putting my booty in the air for half hour after each session. All that fun stuff.

I guess I don’t understand how I can ovulated on Friday then start my period on Saturday? Does that mean I’m defiantly not pregnant? Ugh 😒 such a stressful game to play!
