I can advocate falling asleep after DTD, gives the swimmers a bit more of a chance to swim "downstream" IYKWIM? Also try pre-seed (lullaby Conceptions) as you may just have slightly hostile Cm. If that is the case, you have such a tiny window where CM is ok for the swimmers that if you DTD the day before or even two days before, it kills all the swimmers so it has to be the day OF O. Pre-seed encourages a more sperm friendly cm and actually nourishes the swimmers so.... I also don't agree with stretching the truth to Dr. It takes time to fall pg. I wish you all the best honey.... Look into diet changes (to change the cm acidity etc). Goodluck
