Possible late ovulation


Hi ladies,

Can I please have advice.

I have just come off the pill 2 months ago and have had 28 day cycle so far. This month I've been using opk but it days 14 and both my app says I should be ovulating but all the opk both the cheap ones and clearblue are negative. I'm worried that I'm not ovulating or that I might ovulate later. And if I do ovulate later can I still get pregnant if my cycle is 28 days?
