Hopefully u realised a really really good eggy and you body is preparing itself for pregancy.
At 4DPO I remember i was sat down just watching tv and all of a sudden I had this really really sharp sudden pain. It was so sharp and to early for implantation. I reckon our bodies just know when something is about to happen and it gives us little signs. U know like clues. Because low and behold at 9 and 10DPO I was in alot of discomfort and felt those stabbing sudden pains again and it turned out to be implantation.
I'm 5 weeks 2 days pregnant now so my body was definitely trying to tell me something rite back when I was 4DPO.
I think also when ure actually ttc u notice more with ure body.
Good luck hon. Hopefully ure get ure BFP real soon.
When are you testing or are you gonna wait till AF is due.
I tested at 6dpo 7dpo and 8dpo and all BFN.
That at 11DPO I got a bald positive on first response .
Was using cheepies b4 and didn't get a good positive on them till around 15DPO and even then it was faint.
First response was the one that convinced me.
Good luck.
