Can someone help ?

This is my chart. When inputting info it originally told me ovulation was cycle day 16, but I honestly thought it was 14-15 and maybe it wasn’t 🤷🏼‍♀️🤦🏼‍♀️

However af still hasn’t started I’m normally a 12-13day Lp.

My cervix is high soft and closed, no sign of af

I’m having twinges and cramps

Could I have implanted really late ?

The only thing I’ve noticed last couple of days is weird/ odd cramps and there random times, and today increased hunger.

I’d give anything for a positive .

I’ve had negatives tests 1-2days ago
