2nd cycle post D&C experiences?

Brianna
I had my first AF post D&C on December 2nd, lasted about three days and then two more with just spotting. I tracked ovulation with opk and am 98% sure I got a LH surge. Now I am "late", but have gotten negative hpt tests. 
I would appreciate people sharing their experiences to know if I might be expecting or if my cycle is still just trying to get back to normal. Thanks!
