My husband and I have been trying for almost a year. We have been on an emotional roller coaster ride. We decided to slow things down, and instead of have sex every day, we only had sex twice, once 2 days before I ovulated, and another time the day of ovulation. Also, we used a pillow under my waist to keep pelvis elevated. Oh and I took warm showers before we had sex (not him, I heard the man should not tkae a warm shower before sex because the change in temperture can lower his sperm count). I don't know if any of this worked, but it was something different that we didn't try before. And we are 4 weeks pregnant, so something worked!
I hope these suggestions help!
Good luck
