Ovarian cyst removal and menstrual

Jasmine

I had had an ovarian cyst removed from my right ovary on Mar 16th. I started ovulating on Mar 14th and of course I had sex 🤦🏾‍♀️🤦🏾‍♀️. How long did it take for you’ll to get your cycle back after surgery. Because currently I’m 8 days late. I’ve taken two test and they were negative. I’ve cramped as if my cycle is coming but nothing. Can someone please help? Is there a possibility I could be pregnant or is it just the surgery slowing down my cycle? I’m losing my mind. 😩😩😩 Please help!!!
