OPK Question

Denise • I am 34 years old, married, MC June 2018. Lost fallopian tube 2/19. Hoping for a miracle baby!
I tracked my ovulation using OPK this month, but I never got a surge. Going on day 5 of having sore breasts and now nausea has started happening too. Could I still have ovulated and could these be early pregnancy symptoms? AF due 9/25. Thanks in advance!!
