talking about ovulation here

Anyone's temps just take little jumps maybe .1-.2 day instead of a big leap? Normally i have a big dip (.4 or more) and than a significant rise (.4 or more) but this month i had the dip went from 97.9 to 97.4 but instead of a big rise it's tiny rises. 97.5 yesterday 97.7 today. Do you think i still ovulated? Or do you have to have big jumps for it to be ovulation. No crosshairs yet since my temps have just started rising from the dip. I hate these little rises. I like the big dip the big rise, that way i know it happened.
