2 days late

Marissa
So I am now two days late normally I have a cycle of 24 days but I just under went a Lapo for endometriosis, not sure if that changes up the cycle but this would be my second period since the surgery the first one came 24 days like usual. I want to go buy a test but the idea of seeing that bfn again after 7 months is preventing me! Anyone experience a change in their cycles after the endo surgery?
