Hope this isn't a dumb question...

So I know this may seem like a dumb question because everyone always says the answer but just like most ttc I'm trying to do things perfect. I had spotting with ewcm 3 days ago (on Friday), back pain the following day like I do around ovulation sometimes (usually before), and today I'm having cramping similar to period, I'm think it could be ovulation cramping assuming the back pain wasn't. Hubby and I DTD lastnight (and everyday for the last like 5 days) and I still have ewcm. If I'm ovulating today are my chances good for catching the egg? Should we DTD again today to be sure? I've tried opk but haven't gotten any definite surge. They're staying pretty dark consistently. Today's was the darkest I've had. Thanks!
