Can I still ovulate without having EWCM.

It’s been 8 days since I’ve finished my period.

I’ve had cramping on one side for a couple days and I’ve been having on and off headaches too.

But I haven’t got discharge yet. I’m on cycle day 16. Last cycle I got it on cycle day 14 and had a 29 day cycle and the cycle before I got it cycle day 17 and had a 35 day cycle.

Should I be worried of pregnancy ? Is this the reason I may not be ovulating. Even though I’ve had two heavy periods that were bright red since last sexual encounter ( foreplay.)
