Did I O?

Hi everyone, I'm new here :) I just started chatting this month, and also just started TTC . Yesterday morning my temp was down .2 and this morning it was up .4, but I haven't had any EWCM or really excessive wet CM (sorry, TMI). I did have very light cramps yesterday. Is this normal? I know I have to wait for 3 consecutive days of higher temps to confirm, but I'm just wondering if I should still BD just in case this is an anomaly? I'm on CD 14 now. My cycle varies between 28-33 days.
