Implantation at 4/5DPO, is it possible?

[TTCno3V]

Hi Ladies,

As the title says, is this possible so early on?

I had incredibly bad cramping at 530 this morning for about an hour and it was quite a sharp pain from front to back, quite low down and carried on for about an hour and woke me up. Still having the odd cramp in the same area.

My last child I had very similar pains but more intense and made me collapse and I got my BFP on an IC at 10DPO.

Just wondered if anyone has experienced possible early implantation which has led to a BFP?

Thanks

Yes at 5dpo it could as the embryo has reached blastocyst stage and starts to hatch to implant but mostly certainly not 4 dpo it would be near impossible. Good luck!
