After a miscarriage in November I've had 1 cycle that started exactly 28 days after my 2nd d&c. I needed 2 as the first surgery did not remove the fetus.  We BD during my most fertile days and of course the TWW was too much and I took several pregnancy tests starting 4 days before my period.  I could have sworn that the first test revealed a vvvfl and that was confirmed by other members on glow.   After that test however, the vvvfl disappeared and now I can just tell that AF will be here tomorrow (unexpectedly expected of course).
