Ovulation?

I still have a headache, not a severe one but enough to bother me.  Also, I've been having a lot of twinges and pains on the sides of my abdomen as well as mild low back pain.  Overall I just feel crampy.  OPK this morning was negative so my LH surge definitely was yesterday.  My BBT went up today so if it goes back down tomorrow I'll know that I'm done ovulating.  I'm really really hoping this is it! I'll be testing around July 24th.  The Hubs birthday is the 21st so I might chance it and test early to give him the ultimate birthday present! Unless I have other super crazy symptoms, I won't post again until I test :)  Wish me luck!
