Ovulation with no spike?

So I had a MC 12/15 and this is my first office cycle after. We didn’t try after the MC bleeding stopped but I tracked and saw my ovulation and BBT (which increased)....this cycle I got a positive OPK CD 12 and 13...before my MC I would be able to see a spike in my BBT showing the ovulation but this time on CD 14 I still have the same BBT with a negative OPK...do you think I still ovulated? Anyone else have this happen and still get a BFP?!
