Late period after minor surgery

Je

Hi ladies .

I've recently had minor surgery on my foot so they had to put local anesthetic twice .I was then supposed to started my period 2 days after but I didnt .so the stress goes further as im now on day 9 of not starting !

I've been having orange juice, oranges,pineapple ,you name it ! And I still haven't. I've not had no pregnancy symptoms at all. My period is always on time and sometimes early .its very rear that its late .

To be fair, in June I had minor surgery and I was 2 weeks late .I sill did a test then (negative) .

I really don't understand why I'm so late .
