Ovulation

Sam
Hi! I was just wondering when everyone else ovulates? I'm new to this but last month I had a chemical pregnancy (we weren't really trying) and of course after that I think everything is wrong with me.  I think I had the cp due to late ovulation and a short LP.  I'm on cd16 and still no sign of my lh surge even though I've been testing 2-3 times a day.  My cycle is 29-33 days normally.  Thoughts?
