Is it possible to ovulate early?

My last 3 cycles have been 38 days so I’m not due to get my period until 1st Jan (I know, happy new year and all that 🙄)

Yesterday I was out at a friends baby shower and came across having a panic attack/going to throw up/pass out as soon as I had last bite of my meal. My gums have been bleeding when I brush which isn’t normal for me and my teeth ached on Friday like I was expecting to get a cold, but nothing came about of it.

Is it possible I ovulated early? My CM has been dry since the 16th day of my current cycle. On CD14 I had EWCM from what I can work out?

App says should be ovulating now but I have no symptoms?

Please help!
