Question about ovulation/CM

Becky • 2.28.18 🎀👶🏼 Currently TTC #2 ❤️
I've been taking OPK tests the past few days and never got a positive result, however I have had 2 days of egg white CM being there when I wiped. Doesn't that mean I was fertile? If so, do you think it matters that the OPK tests were all negative? Do you think I have a chance at conceiving? We did it both days anyway even though the tests weren't positive. 
Any advice or opinions would be really helpful!
