can you ovulate 4 days before period?

Kaitlyn
So my husband and I are TTC, I have PCOS, but have been VERY regular! 27 days! I am currently 4 days late. I had a BFN this morning, but I'm wondering if it's too soon. I had lab work last week and my LH was super high!!! So I'm wondering if I had my LH surge and then ovulated. My husband and I BD the two following days and now I'm 4 days late. What do you guys think? Could I be pregnant still or am I just a crazy person hoping too much?
