[babyrose]

Im on day 16 and I think around 4dpo maybe 5. And im getting some cramping but not due af til 23Feb is it too soon?

It's too early to know but
If it does turn our that you are pg, you can go about being insufferably smug about knowing so early! For now, though, you'll have to suffer through the two week wait like the rest of us. Keep your fingers crossed.
