17DPO, 3 days late, BFN 😣😣

I’m pretty sure I ovulate on CD11 due to a dip then spike in temp, I normally ovulate on CD12.

So today I am 17DPO, my usual luteal phase is only 13-14 days and my cycle is usually 25-26 days long.

Because I ovulated early I expected my period to come CD24-25 however AF hasn’t arrived yet and I’m now on CD28/17DPO.

I had cramps at 8DPO then ‘tugging’ cramps everyday from 12DPO, mild nausea, bad headaches, fatigue, backache and lots and lots of spots 😞😞

I tested today and got a BFN! Does this mean I’m out? Has anyone had a BFN at this stage and then gone on to be pregnant? It’s very unusual for me to be late! 😞😞
